Message:: [QUOTE="Seattlite86, post: 11219073, member: 59737"]Okay, so I did a blind test with my wife. I put a set of coins into a separate ziplock bag and had her sniff them. I included another set of coins that had sat in the large pile. She said she could detect a very faint trace on the ones that I aired out, but interestingly, could not detect it on the coins that sat in the container of what I’ll refer to as “control sample.” I then had her pull each group out of the ziplock bag and smell the coins. She was unable to detect the scent in any of the piles. I sampled each set in the same way, and could not detect anything while they were in bags. When I pulled them out, I could detect a faint trace on the ones that were aired out, and could definitely smell them on the control sample. I think one of the things I did not control well was the amount of coins in each sample. The aired out coins had the largest sample, while the control sample had the smallest. I think that may have impacted our ability to smell the smoke scent. My semi-scientific conclusion: all coins should get a 1-hour bath in distilled water, then fully dried, and then air them out for 24-48 hours. I’ve elected to not purchase acetone, as we recently moved and have been spending too much money lately.[/QUOTE]
