BTW, I use a sharp knife (mini with small thin blade) to pry open some airtites. I use the long edge and gently nudge it into the "crack" and gently twist until I can get a finger nail in to do the rest. Love airtites to protect the coins but sometimes they are a b*tch to open.
Yes they are. My nickel ones are really easy. These dime ones don't give you any place to help you open them. I quit. Lol
They both look like proof coins to me. The 57 I’d say is in the PR-65/66 range based on the photos. The earlier proofs don’t always have the full cameo look of the moderns, this is a result of how the dies were prepared, only the first handful or so had the cameo look which is why they are so desired and carry such a premium. From the looks of it, the 57 was struck with a newer reverse die than the obverse.
How is it that different sides of the coin have different dies? New and old Like you said about the obverse and reverse? So each side of the coin gets struck at different times?
No. The obverse die and reverse die are individual dies. If for instance the reverse die gets worn, they replace that die and leave the obverse die in the coining press and continue minting coins.
Well they are always different dies... they start off as a matched set of new dies, but if something damages the obverse or reverse die, they replace the damaged one, not necessarily the pair. It’s not very unusual to see proofs of the day with a full cameo on just one side of the coin. If you’re lucky, the cameo is on the obverse.
No Shrews there are two dies Obv and Rev. When you hear or read in here about die marriages it how the mint paired dies. Or re used a die. So like in half dimes as well other series you can have a obv #4 and Rev D. Meaning they used the #4 obv die and the D rev die. As an example.
Like my 62. That has cameo on reverse and obverse. Is because what was said earlier it's more modern than the early type?
