Harsh cleaning, or just innocent hairlines?

She looks more like a Clarissa

ambro51

Yes. She is Charlotte. And that is typical Charlotte die preparation, they finished the dies by rough grinding. You can also see how the dies were rusted and the wandering die crack on the reverse. I like Clarissa for a name, I've got an 1853 C firmly in my sights! I love your 55C, that shelf doubling on the obverse letters is super!

I thought that is was struck thru...... what is shelf doubling?

I like yours, I agree with the others, die polish lines.

I only have the one.

Shelf doubling...Longacre doubling....its the same thing. Its not fully understood exactly.... most of Longacres designs CAN show this from time to time, but its an interesting feature and though it adds no specific value to a coin...it is interesting. Most of the time its seen on the lettering, though on dollar gold you can see it on the wreath and portrait as well, Im not familiar if it shows up on his other coins as well, in that manner. Probably a technique he used to allow the metal to flow better into the sharp lettering he preferred, and it was done by cutting an further recess on the main hub. When the working die was fully struck, this would cause a small shelf to appear. Dies were always 'finished' prior to use...some mints used different methods of doing this. Philadelphia, San Francisco and New Orleans done it better, Charlotte and Dahlonega usually just roughly ground the die...though sometimes the dies were used Raw, in which case the doubling would be very apparent. On the 51 C I posted, you can see this on the portrait and stars....on the 55C its more visible on the lettering on the obverse.

As the dies were used, especially if they had clashed, they were lapped (reground and polished) and this effect wore away. On gold dollars, every date except 1849 had the date added to the master die, which was struck from the original hub. The date was then added every year to the master die, so that all the working dies had the date in exactly the same location...though styles and sizes changed quite frequently. You'll never see the longacre doubling on the date.

If anyone has a better explanation of this, chime on in......

here you see it on a very hammered strike on an 1857, it joins the wreath tops together;

Thanks for the explanation Ambro, I've never heard of shelf doubling until now.

Nice '51-C Ambro... and yes, those are die polish lines. The '59-C is notorious for its crummy strike, although the '55-C and '57-C tend to come even more consistently worse. The mint just couldn't seem to get things right w/the thinner planchets. The '55-C & '57-C below are actually two of the better struck/planchet combinations... on many examples, parts of the dates are illegible, not to mention unsightly planchet roughness & rust issues.
Clarissa looks like a doll
