Some of the ones I have are the mascot coins from the 2010 Olympics and a few others like the 2006 breast cancer quarter, etc. (I've already destroyed one of the 2006 ones!) In some cases, over time, it looks like the resin begins to yellow. Report this Post to the Staff

kuh_85 Pillar of the Community Canada 2366 Posts	Posted 07/01/2015 03:32 am I removed a loonie from the stuff by dropping it in boiling water. Took a bit longer than I expected but eventually came off easy. Haven't dared try it with a coloured coin though as I've heard the colour comes off as well. Is that what happened to yours?

trimble Valued Member Canada 299 Posts	Posted 07/01/2015 12:45 pm Lucite? Sure, that works. :) I didn't use the boiling water method, although it crossed my mind. I was worried about the colour too. I tried using a zip knife to carefully cut near the edges and ended up scoring the coin face a bit. I still have the damaged one so may do the boiling water method and see what happens to the colour as a test. Report this Post to the Staff
SPP-Ottawa Moderator Canada 10456 Posts	Posted 07/01/2015 12:53 pm I can remove the 2004 Poppy bookmark coins, but the 2006 proof Olympic loon has been a tough one... I thought about taking it into work and giving it a liquid nitrogen bath "Discovery follows discovery, each both raising and answering questions, each ending a long search, and each providing the new instruments for a new search." -- J.

trimble Valued Member Canada 299 Posts	Posted 07/12/2015 8:44 pm SPP-Ottawa....your suggestion of cold (nitrogen) seems to work on my trial lucite coin...I tried sticking it in the fridge freezer section, forgot about it and a few days later knocked it to the floor when I was reaching for something else. It was on a poppy coin from a bookmark and both sides of the lucite popped off. A small bit of the colour on the poppy also came off. More testing required! Report this Post to the Staff
