Pallets & crates. Truthfully, I don't see much else on the floor at the Philly Mint (walking distance for me; I go through all the time) which warrants nails rather than machine bolts.
If they really want a good marketing gimmick they should slab a Yap stone and put it on display in their lobby. But I suppose there would be a number of logistical/engineering challenges with that.
You missed your opportunity. It's back to 30 grand now. I wonder, when they sent that in to be graded, what the declared value of it was and what the cost was for that value.
I don't believe metal can either enter or leave the building in an employee's pocket. The struck nail probably had to become part of an outbound freight shipment, and the guilty employee (or one of them) handled the freight outside the building. Just a guess, though.
So please don't tell me you're justifying "nails and crap" falling into the dies at the United States Mints? Where quality control is "suppose" to be at exceptional levels! You said: That means that anything that falls from above can fairly easily get between dies. Aren't those die machines enclosed for safety reasons? That dime/nail strike was extensional!
The last time I saw actual coins being minted, admittedly some years ago, there was NO COVERING WHATSOEVER over the coining presses - open to the ceiling they were, where maybe some jabronie is installing a duct or a fan, or ANYTHING. Now, who has seen the same deal post-9/11, the new tour?
Okay, you convinced me. So now I picture the United States Mint looking like an industrial warehouse with crap everywhere. Thanks for that image!
When I last saw it, and we're talking probably 1992-ish here, AT THE VERY LATEST, that is an accurate description. Philly mint.
These days, it's almost antiseptic down there. You view the floor from probably 40ft above, in a self-guided walking gallery with exhibits all around.
Some of the new bitcoins have wallets on them... hypothetically you could slab your entire net worth and carry it around with you.
