JUST out of curiosity has anyone removed silver coins from encased plastic type material ? I have a few bu coins in a pen holder paper weight encased in clear plastic..I'm tempted to get them out but probably impossible, chances are the plastic is on like cement.. anyone done it before, maybe a big hammer  |

It's probably lucite. There are more physics-savvy people here than me, but I would think that if you melted the lucite (how? I haven't a clue. Not over your kitchen stove, though; DON'T try this at home) you'd have a better chance of extracting them. But why do that when you can duplicate them by buying similar coins much cheaper than replacing your house. Whack the block with a hammer? Chew them apart with a Dremel tool? Sounds like a lot of work to me!

No matter how hard you work at it, the lucite will remain on the coin. There is no real way to remove it. The coin is damaged.

It's not damaged, it's protected in a top-of-the-line airtite! ;)

Hey, were do you go to have something like that encased. I have some old shrapnel they pulled out of me and would love to have it in Lucite.

Hope one's not that great Canadian Honker in flight. That bicentential is to neat to entoumb. Love the simplicity of that design.

Might make for a great experiment. Never tried that but here is an idea but if any coins are worth something, might not be to good an idea. First cut off a small piece on a corner. Sumerse in Acetone and see if it disolves. If that piece does melt, then go on to the next step. Now cut away as much plastic as possible with a Dremel type machine. A saber saw might work to but usually not to accurate for delicate work. Then summerse what is left in more Acetone and the coin(s) should be free and without any plastic on them. MAYBE.
Prior to this attempt you really should go to the SEARCH tab at the top of the page and type in Acetone, Coin cleaning, Cleaning coins and/or similar topics to learn all the cautions and methods of the usage of Acetone.

When I was a kid I tried to get a silver BU Canadian dime out of a lucite key chain (you've probably seen them). I used the hammer approach and the lucite does/did stick to the coin, so it was just melt value. A real shame.

Use a band saw to remove as much excess plastic as possible. Then put the coin/plastic in liquid nitrogen. It intense cold will make the plastic very brittle. The large differences in contraction between the two will also pop the plastic loose from the surface of the coin. Remove from the liquid nitrogen and tap gently with a hammer. The plastic should shatter and come away from the coin.

Thanks for the tips, I may try just out of curiosity, and plus I do have access to chemicals that will freeze the plastic will take photos before and after.. j
