There are several ways to open a plastic coin case, but it's important to note that you should never remove coins from their cases without a good reason. Coins are often stored in plastic holders to protect them from degradation, and removing them can reduce their value. If you do need to open a plastic coin case, you can try using a utility knife to carefully pry around the edge of the capsule, making sure to go slowly and work your way around the entire edge. You can also try using your thumb or fingernail to feel for the seam of the case and then use your fingernail or a thin blade to carefully pry the two pieces apart. Always handle coins with care and consider wearing protective gloves to avoid contact with the oils on your fingertips.

What You'll Learn

Using a utility knife
To start, select a grooved area level with the coin to begin. Place the edge of the knife in the groove of the slab. When it is in the groove, turn the knife so that the blade faces the opposite edge in the groove and apply pressure while turning. The goal is to pry apart the front and back of the slab. Repeat this process, moving towards the corner of the slab until the coin is released.
Another method is to use a utility knife to carefully pry around the edge of the capsule. Insert the blade tip between the top and bottom halves of the capsule at various locations around the coin edge. Once you have a slight gap around the entire edge, you can use the blade to pry up the edges. Make sure to go slowly and work the entire edge of the capsule, not just one side. Once the halves are pried far enough apart, you can separate them with your fingertips.
It is also possible to use a utility knife to wedge the blade between the plastic. Then, carefully and gently rock it using a fulcrum action. This will help to separate the halves of the capsule. After the sides are separated, the insert will bend, and the coins will pop out. If they don't, you can carefully push them out while wearing thin cotton gloves to protect the coins from the oils on your fingertips.
When using a utility knife to open a plastic coin case, it is important to use a knife with a sharp blade that you can get a good grip on. A pocket knife or a utility knife with a fine, strong blade is recommended. Avoid using a kitchen knife, as it can slip. It is also important to work slowly and cautiously, especially when working around the seam of the capsule, to avoid damaging the coin or the capsule.

With your thumb/fingernail
If you're looking to open a plastic coin case with just your thumb or fingernail, there are a few methods you can try. Firstly, identify the seam of the case by running your finger lightly up and down the sides of the case. You should be able to feel a slight ridge or offset where the two halves of the case meet. Place your thumb or fingernail on this seam, and slide it around the circumference of the case. Apply some pressure and wiggle your nail back and forth to start prying the two halves apart. You can also try placing the case on a soft surface like a cloth or towel, and then using your thumb and fingers to bend the case slightly, which may cause the coin to pop out.
Another method is to use your fingernail to start the separation of the two halves of the case. Find the seam with your finger, and then use your fingernail to carefully get in between the two halves. You can then run your nail around the seam, prying the halves apart as you go. This method may require a bit more force, so be careful not to break your nail or damage the case.
If the coin is stuck in one half of the case, you can try a similar method to the above. Use your fingernail to carefully get between the coin and the case, and then gently pry the coin out. You can also try placing the case between your middle finger and thumb, with the coin facing down. Then, hit the heel of your hand against a hard surface, which should cause the coin to drop out. It's recommended to place a soft cloth underneath to catch the coin and protect it from damage.
Finally, if you're having trouble getting your nail between the seam, you can try using a tool to help start the separation. Some people suggest using a single-edge razor, a knife, or the stub end of a nail file to get between the halves of the case, and then using your fingernail to finish prying the case open. However, be careful when using sharp tools as they can deface the edges of the case or damage the coin. With a bit of patience and the right technique, you should be able to successfully open a plastic coin case with just your thumb or fingernail.

Freezing the case
Freezing the plastic coin case is a popular method to remove the coin without damaging it. The idea behind this method is that the cold temperature causes the silver in the coin to shrink, making it easier for the coin to be removed from the plastic case. This method is also known as the "freezer trick" and is considered a "tried-and-true" method by some coin collectors.
To perform the freezer trick, place the plastic coin case into the freezer compartment of your refrigerator. Leave it there for a sufficient amount of time, allowing the cold temperature to act on the coin. The duration of freezing may vary depending on the coin and the case, but it is generally recommended to leave it in the freezer for at least a few hours.
After removing the case from the freezer, you may notice that the coin has started to shrink slightly due to the cold temperature. At this point, you can try to gently remove the coin from the case by hand. Wear cotton gloves or use a soft cloth to handle the coin and avoid transferring any oils or fingerprints onto the coin's surface. Gently twist the plastic case or apply slight pressure to separate the two pieces of plastic.
If the coin does not come out easily, you can assist the process by using a thin object, such as a single-edge razor or your fingernail, to carefully start the separation of the plastic pieces. Once a slight gap is created, you can use your fingernail to finish prying the case open. Be cautious during this process to avoid damaging the coin or injuring yourself with sharp edges.
While the freezing method has worked for some coin collectors, others have reported that it did not work for them. It is important to note that the effectiveness of this method may vary depending on the type of coin, the tightness of the case, and other factors. Therefore, it is recommended to exercise caution and consider alternative methods if the freezing method does not work for your specific coin case.

Twisting the plastic
If you are set on twisting the plastic, it is recommended that you wear safety glasses to protect your eyes from shards of plastic. You can place the case between your feet on the floor, or, alternatively, place it horizontally in a vice grip and twist. You can also use a tool to assist with twisting, such as a screwdriver or a two-by-four with a slot in the end.
If you are using a tool to twist, it is important to select a grooved area level with the coin to begin. The edge of the tool needs to be in the groove of the slab. When it is in the groove, turn the handle so that the edges of the blade are facing opposite edges in the groove and apply pressure while turning.
Some coin cases may be easier to open than others. For example, one source suggests that coin cases from 1999 onwards may be easier to open using twisting methods.
It is worth noting that there are other methods for opening plastic coin cases that may be safer and less likely to damage the coin. These include using a knife to gently pry the plastic apart, placing the case in hot water, or using a suction cup tool.

Using a soft cloth
To open a plastic coin case with a soft cloth, you can follow these steps:
Firstly, it is important to wear protective gloves to avoid any contact between the oils on your fingertips and the coin. Place the plastic coin case on a soft cloth to ensure a stable and protected surface. The cloth should be placed on a flat surface, such as a table or a pillow, to provide a comfortable working area.
Next, identify the seam of the plastic case by running your thumb or fingernail around the edges. Once you feel the seam, carefully apply pressure using your fingernail or a thin blade, such as an exact knife. Gently work the blade along the seam, prying the two pieces of plastic apart. It is crucial to perform this step slowly and cautiously to avoid any damage to the coin or the case.
As you start to make progress, you can begin to carefully separate the two pieces of plastic. Continue to work slowly and use the soft cloth to provide a gentle surface for the coin to rest on. If the coin is particularly difficult to remove, you can try placing the case in the freezer, as this will cause the silver to shrink and make the coin easier to remove. Alternatively, some suggest using a soft cloth or towel on a table and wearing cotton gloves to push the coin out.
Once the coin is released, use the soft cloth to handle and transport the coin, avoiding direct contact with your fingers. This will help protect the coin from any oils or dirt that could affect its condition. By following these steps, you can successfully open a plastic coin case using a soft cloth, ensuring the safety and preservation of your valuable coins.
