One of the primary uses of xylene is to clean up & remove paint. It works on paints that acetone won't work on, as well as of those that acetone...
A prolonged soak in acetone will remove or help remove some paints, but no means will it remove all of them. Xylene would be a better choice for...
mill rat - A couple of things - PCGS is also known for having dipped, rinsed, cleaned, conserved - pick your term - coins without ever being...
They didn't cease operations for quite that long. The San Francisco mint began striking coins again on Sept. 1, 1965. The first coins struck were...
About the only comments I can add Tom is that Conder's book puts the advent of the blue holder in Nov. '98. You might want to talk to him because...
Given that your coin does show signs of color it's also a good possibility that it was a plated or gold wash counterfeit. The thing I find unusual...
I'm well aware of that, I collected original mint sets for decades. And finding gem examples can indeed be difficult. But the coins having some...

I looked through all of them and your coin does not match anything listed. Your coin is similar to what a combination obv BG 420 and rev BG 408...
Not my image at all, that's the original image that the OP posted. All I did was show it full size and crop it.
desertgem explained it quite well. But let me add something else here. When that reply was made on the other forum that the coin looked dipped,...
Not when you look at it full size. When you do, you can see where something was gouged into the metal starting on the left hand side and it left...
I don't think so. If it were a strike through the edges around the depression would not be so sharp and they would not appear to be lifting up and...
Sure, the PCGS coin sniffer can only do what I described in post #11. And none of the other processes used in the Secure Service can detect proper...
You cling to the older ways ? You sure ? I ask because cleaning coins is about as old it gets. For centuries collectors all over the world cleaned...
