That's a crazy collection fren, very nice!

>that would be super neat if it were an error that occurred during the minting process but considering the age and composition, i would imagine that it is probably some sort of oxidation or corrosion
Could very well be that, and that was my first guess too once i cleaned a bit the coin, but what makes me turn on the gas on is it's extra material, there is no missing material, only added "concretions". Maybe zinc degrade this way idk, in truth i've no idea because i don't have other old zinc i believe.
But if it was let say copper, i'd immediately think of added material, it's very clear once you pass your fingers over it, it makes little "hills" but with no crevices.
Lemme fetch my jeweler loupe fren, i'll try to give you a close up pic in better definition. brb!

>to where there are the various auctions or sales of this particular coin and some have some aging that kind of look like yours.
I must be blind because i don't see any similar aging on the contrary kek.
