I am not sure what exactly it is you are looking for, but you can check a bank supplier and see if they have what you are looking exactly. Also try office supply stores in the area and see if they have the kind of plastic coin bags that you want. Go to your bank and see if they have any spare bags you can have. I have done this many times.

This coin is actually a half-cent coin. It is actually a lady with the powdered wig on the coin. To check if this is right, compare your coin to http://en.wikipedia.org/wiki/Half_Cent_(United_States_Coin)
