stgaudens New Member Germany 40 Posts	Posted 06/26/2021 2:09 pm Hello, I found this article about coin doctoring and now I am worried about artificially toned gold coins: https://coinweek.com/opinion/commen...eat-coins-2/ I have read that among other substances, iodine has often been used to artificially make a gold coin look old & crusty. Now I have some questions: 1. I am wondering now: how can real old, dirty gold be distinguished from these doctored coins? And is this coin doctoring only a rare occurance on (rare) US coins or a widespread problem affecting all kinds of historic gold coins? 2. Here are several examples of different looking old gold coins I could find on the internet. Do you think they look authentic or doctored? https://www.PCGSeurope.com/cert/42268119 https://www.NGCcoin.com/certlookup/5702965-003/40/ https://www.numisbids.com/n.php?p=l...4069&lot=121 https://www.sarc.auction/FRANCE-Nap...45_i40778552 Report this Post to the Staff

tdziemia Pillar of the Community United States 7967 Posts	Posted 06/27/2021 08:36 am Interesting article. I would only comment that the color of the U.S. $5 coin looks abnormal, and that the last coin looks like it was dirty and underwent a partial cleaning at some time in the past (i.e. nothing nefarious going on). I have only a small number of gold coins in my collection, mostly far older than these, and all look like I expect gold to look (i.e. gold colored, with no toning, except for one which I think is less pure, maybe 50-60%).
