that coin would die if something wasn't done.... BTW - how did you know the G in GDJMSP stood for Guru? GURU Doug... Now guess the rest of the letters...
You either have a short memory or must not read a lot Harry. I have forever and always advocated removing contaminants from a coin in order to prevent additional damage
I do a little metal detecting and quite often dig old copper. I've used Biox in the past and to be honest it scares me a little... Over a year ago I ordered some Biox and Renaissance Metal De-Corroder from Dirty Old Coins. Neither come with any real instructions, and while the consistency is different, I'm not entirely sure of the actual difference between the two products. I decided to test the Biox on some junk copper coins I had lying around, and in it's undiluted state it will turn copper coins bright pink fairly quickly. It will also give the coin an odd feel... it doesn't quite feel like metal anymore. I also tried it on some super-encrusted ancients I got in one of those uncleaned lots you see for sale on eBay all the time, and left them in the Biox for an extended period of time. One copper coin became almost powdery... there's no other way to describe it. Maybe the stuff isn't meant to be used straight out of the bottle, but you'd think they'd put something on the label. I won't even consider using it on any of my valuable coins and it's been sitting on my shelf (right next to the Renaissance Metal De-Corroder) for the past year.
