So, Doug, do you think the changes you saw when copper coins were treated with acetone were genuine chemical changes or due to removal of oil,...
Pure acetone won't hurt the coin and will remove PVC residue. However, if copper has a layer of oil on it, acetone will remove that as well so...
I've had Lincoln cents in Whitman folders do more than just tone. Some had active corrosion at the rims and edges. Wiped off the verdigris, put...
How else would coins retain quality germs? :yack: Cal
The whole Arkansas series is known for its lack of luster. Probably had to do with die polishing (or lack thereof), or planchet composition or...
Here are the grades from Stacks and PCGS. Stacks graded them each aChBU. That should translate to MS62. When I looked at the coins before...

I think few folks dispute a grade on a coin that they submit that comes back graded higher than they expected. Perhaps they would for an...
I agree the government should stay out of setting coin auction premiums. I don't know that there is collusion (which would be a crime), so it's a...
I think Legend has a winning formula of having internet-only auctions with 10% buyers fees and live auctions for more expensive coins with 17.5%...
Heritage maybe, but I know that some of their execs opposed going from 15% to 17.5% a few years back. I don't think it will happen at Great...
See link below. It was 17.5%. New rate becomes effective after the ANA auction. They try to present it as though it's a good thing for buyers....
Yah, you'll need some thick mittens to handle your slabs. :cool:
