If frosting lasted 100 strikes and each die lasted 3,000 strikes and they made 3,950,762.
1,300 dies.
1,300 x 100
That's 130,000 frosted proofs.
The rarity seems more like each working hub was pickled and gave impression to as many working dies as needed each weakening in frosting share to the next working die.
I only say this to possibly explain this North East rotation tilt seen pulling the L away from the rim and up from the bottom, the eyelid coming down and the top of the horizontal 4 end closest to the rim. The surface frosting is showing greater the more north it is and narrower the more south it is. The surface frosting exactly mimics the direction the tilt turned.
