I was going through some coins on the weekend and I opened up (for the first time) one from the Singapore coin fair that I purchased awhile and I discovered the following... Yes - they are on the coin itself.... Not happy Jan.... but oh well.. that is life. I should have checked it out when I got it in, but was so flat out earlier in the year that I have only just started looking at things I got in 6 months ago. So what to do? If i send this for conservation/cleaning at NCS do you reckon that will be the only real method of sorting out this coin without any damage etc? Any tips from the pros? Thanks!
