Coins encased in acrylic (exonumia)

Anybody here collect coins or banknotes encased in acrylic (resin)?

I have a bunch of these, stuff I picked up at shows over the years.

Sometimes the coin is a nice collector's piece; maybe a Walking Liberty half or an Ike dollar.

Sometimes the coins are uncirculated, sometimes cleaned.

Some of the pieces are used for advertising and have a business name or slogan. Others are just paperweights.

Any other collectors here? I'd love to see what you have and swap some.
