I just got one from a local dealer. It passed all tests, as far I know but one. My calipers are not spot on accurate, and measured 32.67 mm, (actual 32.77)
My scales are kitchen scales, and it weighed 34 g. (actual 33.93)
The only thing that didn't seem right, is the magnet showed no resistance at all. I compared to a 999 gold coin, and it had resistance.
OK, so I just tried it on a Double Eagle and it is 90% gold and 10% copper, and it had no resistance either.
I feel a bit better, tho I may hit another coin shop and have them check it. I do like piece of mind.
