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:
That's a good start. However, vaults have been flooded by plumbing leaks or fire sprinkler activation too. So having a box high off the floor is...

Very nice. And if the probes are positioned on the edge, but aren't positioned directly across from each other? In other words, how will...
So, what happens if your probe placement on the edges is off a couple of degrees from being on a diameter chord? Measured resistance should be...
One annoying thing about submitting coins for crossover grading is that if the coin does not cross, you're not told what grade they think it is....
As Doug mentioned, checking physical characteristics of the metal won't distinguish genuine from fake coins cast or struck from the "real stuff"....
I have a few hologram coins from Kazakhstan. They're part of the flora series. I think they do a great job in the mint and like it that the...
Probably the thread should be "Post your government-authorized hologram coins". This would hopefully avoid the huge number of post-mint hologram...
I know Canada, Australia, and Kazakhstan produce hologram coins. I think the proposed thread is a good idea. However, there are private...
Possibly some automated imaging system that they used to have, perhaps part of a security or tracking system. In the receiving room, coin may...
Stumbled across the image linked below of an 1802 half eagle, cert. no. 06630159, on PCGS website. Why would they put such an image on their...
