I saw a lot of four S. Korean 1968 One-Won coins for bid at eBay a few years ago. I won the lot and sent all four to NGC for grading. Three came back in MS-65 and the one shown below in MS-66. Currently there are 31 in the NGC census at this grade and only 3 higher at 67. Since the listing at eBay noted that the coins came from a mint bag, I contacted the seller to ask if he still had the bag. He did, surprisingly, and I snagged it for an extra $30. After few years later, I got the idea to place these two in a frame or a shadow box of some kind. I got the idea after seeing someone else who had done this with a mint bag and a CC Morgan Dollar: Here is my shadow box. It's a pricey German "Lindner"-brand product that uses plastic film sections that trap whatever you're trying to display between the two halves of the frame. This is the largest one I could find, at a 9" X 7" interior. Anything requiring a larger space would have ended up in a regular framed display, like the one above. I like this Lindner floating frame display because you can see both the obverse and reverse of the coin. Reverse:
I don't have anything like that but I think it is nicely done. That is a great way to display all these related items.
I have seen similar set ups and they make for nice displays. I like that bank bag! Modern coin mart does a mini version of this usually with an informative card on one side and a slab on the other. These are in an inexpensive plastic case. I once owned a hand heller from Hall in a display such as this, but I think they do them for bulk submissions sometimes as I've seen just "genuine" ancient coins in similar packaging.
Yep. Many of these "floating frames" are much smaller and hold just one/two coin(s) or one slab. This one I have actually looks really nice as a hanging frame against the wall.
