DIY Coin Holder (2x2 Card Holder)


Supplies for coin collectors are not readily available where I come from. Most, if not all, supplies for the local coin collector here in the Philippines are imported from other countries and come with a premium. Its really a challenge to find a ready made coin holder made specifically for local coins. Most supplies i have seen online are for US coins that can be used for some of the local size coins.

A coin holder is a 2X2 piece of card with one edge closed and folded over. It has a plastic lining and serves to protect the coins from fingerprints and dirt. I was able to make my own coin holders from locally available materials from the local office supply store. Please note that i have not tested any of the materials for any compounds that might be harmful to coins, which means my holders do not conform with numismatic standards in coin storage and should not be used for high value coins.

Disclaimer: Please follow these instructions at your own risk. I will not be held responsible for any accident or injury you may sustain while doing this DIY project.

Lets get started. First of all, you need to prepare your materials.


  • MATERIALS AND TOOLS




1. A coin
2. Poster board
These come in large sheets. You will need to cut them to size.


3. Transparency
4. Scissors, stencil knife, pencil
5. Cutting board and flat clinch stapler

  • PROCEDURE



Step 1.
Cut the poster board and transparency to 2 x 4 inch size pieces.


Step 2a.
Fold the poster board crosswise with the white side out.
You will end up with a 2x2 square.
Step 2b.
Fold the transparency crosswise.
You will end up with a 2x2 square.

Step 3.
Take your coin and center it on the folded poster board and trace the coin.
Use an old coin of the same size to do this so that you wont have smudges on your subject coin.

Step 4.
Cut the traced circle using a stencil knife.
Be careful not to cut yourself.
Cut the board through and through.



Step 5.
Insert the folded transparency into the folded poster board.
Make sure closed ends are on the same side.
You now have a coin holder.
Take your coin and carefully center the coin in the holder then fold.

Step 6.
Align the coin such that the top should be at the folded side of the holder.


Step 7.
Take you flat clinch stapler and staple the 4 sides close to the coin.

You will end up with something like this.
The four staplers near the coin are usually enough.
I just like to add extra to flatten the holder.
You will notice some excess transparency protruding from the holder.

The back side. Notice how the staplers are flat instead of the normal arch?
Although normal staplers will do, it's best to get yourself a flat clinch stapler
so that you can have a flatter coin holder that is easy to insert in coin albums.

Step 8.
Take your scissors and cut the protruding transparency.

Step 9.
Take a pen and label you coin holder.

I usually label my coins this way.
Upper left is year of minting.
Top center is the series (Optional)
Lower left is the face value of  the coin.
Lower right is the country of origin.

Another example of how I label my coins. You may do so differently.
As far as i know, there is no standard for labeling.
Notice how the cut out is larger than the coin?
Sometimes I like to do it this way.
It allows me to see the edges of the coin and not just the faces.
Just use a larger coin to trace the circle.


I don't label the back side, unless there is something about the back that needs noting.


And you are done! Congratulations in making you own coin holder!

Please leave your comments and suggestions below. My procedure is in no way perfect and i am open to your suggestions.

Enjoy!

Coin Collection: Minting Error

1983 50 Centavo coin. Flora and fauna series (1983-1990) Philippines



The first minting of the Philippine 50 centavo coin of the flora and fauna in 1983 had a major error on it. As always Banko Sentral was quick to correct the error. I don't know how many error coins were actually put into circulation, but according to some websites, this error coin is quite rare nowadays, but the price is still relatively cheap.

Can you guess the error?



Bank Sentral made an error in the Philippine Eagle's scientific name. Can you guess which if the above is the mistake?
The left coin reads, "PITHECOPHAGA JEFFERYI." The one on the right reads, "PITHECOBHAGA JEFFERYI."

Did you notice the difference? The P and B. so which one is the error coin?

The one on the left is the correct one. The one on the right is the error coin. I didn't know about this error until recently and I am lucky enough to have lots of this error coins in hand thanks to a forgotten bag full of flora and fauna series coins at home. The error coin was still legal tender before and was accepted for trade.

I don't know the going rate for a good 50 centavo error coin, but i read in a forum once that some people are willing to trade fairly rare foreign coins for this. I have approximately 20 of these some are very ugly, but some are still in good condition. If anyone wants a coin like this, trade me something for it. hehe. O_O

This error coin in still quite good in appearance, but you can clearly see the scratches on the coin. The correct coin at the top is better looking, but then again the error was minted first, making it older the the correct coin.


A better closeup of the error.


Its kind of cool to have one of these and I am a proud owner of a piece of history that tell me even banks make mistakes. >_<

Below is the coin I separated. For me this is the most visually appealing of the bunch.
