Copper has a lot of quirks being a relatively softer metal. It tends to flatten with wear, and is prone to more PMD and corrosion. While you certainly have a unique collection, most of them still have a lot of meat on the remaining bones.
The Comet. S-271. Looks like Noyes 1e with the crack at the neck extending all the way to the throat but not into the field.
This may be my best dateless acquisition yet. And I already acquired a dateless 1803 NC-1 earlier this year. I'm leaving the attribution off for the time being as I don't want to influence anyone confirming my find.
Awesome! Can’t wait to hear what it is. About the 1803 NC-1, I’m probably going to start hunting for one along with a dateless 96 (which I have studied reverse diagnostics for). Is the wide fraction a giveaway or are there other reverses with that fraction?
The Obverse distance from the hair and dentils are significant. The Reverse ribbons and berries are significant. ps I'm talking about the Liberty Cap. If you're talking about the 1803 NC-1, Then the small fraction with the high 1 and wide denominator is one diagnostic, The easiest on is the top leaf gap under the center of E(S). The leaf under D left of the upright and the inside outer leaf of the third outside group on the right are all significant and potentially diagnostic.
S-281 Reverse - Top left leaf under the right curve of (E)S. All the others are at the outer edge or S or further.
Whoa - an S-39 even in this condition is a high 4 figure coin. I’ll confirm the attribution using a Photoshop overlay later.
S-286 with first 1 distant and 811 closer. The only other variety is S-287 with evenly spaced digits. Reverse under curve of (E)S and dash under (N)E on the S-286 and the right edge of S on the S-287. Only a single die state.
