Best State Quarter Frame

Nice research Mila ! Those were some pretty cool & creative frames.

The only thing I can add is if you want a frame that allows you to see both sides then you might also want to checkout wall frame holders from airtites at http://www.airtiteholders.com/

Here is an idea. Get a piece of glass the size you would need to display all the coins. Lay down one each with one face up and one face down next to each other. Check out where to buy liquid plastic such as hobby shops. People use it for that stuff called decopage or something like that. Put the glass in a frame, pour the liquid plastic over the coins, allow to harden. Make sure there is no room for the plastic to leak out between the frame and the glass. You will now have a framed coin display where you can see both sides of the coins and never have to worry about the coins tarnishing, toning, discoloring.
As to the glass and frame that is something you can probably find at Walmart, Kmart, Target, etc. The only thing is to first lay out the coins to see how much room you'll need so that is the size of the glass and frame you need.
