Fosdick Posted March 25, 2019 Share Posted March 25, 2019 Is it possible that the dies could create hairline scratches? I have several coins where the scratches appear to be rising above the surface of the coin. Link to post Share on other sites
Member: Seasoned Veteran DWLange Posted March 25, 2019 Member: Seasoned Veteran Share Posted March 25, 2019 Yes, scratches in the die will appear as raised lines on the coin. Link to post Share on other sites
Just Bob Posted March 25, 2019 Share Posted March 25, 2019 They are very prominent on the 1964 SMS Roosevelt dimes. They are called "Die Polishing" lines, but they are more like "Die Scratching" lines, in my opinion. I always thought that just a little more time and effort on the part of the die finisher could have turned out some really nice looking coins. Instead, they look like they were produced in a rush. On a different coin, the lines may have given it "character." On this particular coin, they make it appear unfinished and less attractive than it should have been. Link to post Share on other sites
Fosdick Posted March 25, 2019 Author Share Posted March 25, 2019 Thanks for your reply Bob & Dave. Next question, of course, do the die polishing lines detract from a grade the same as ordinary old hairline scratches? Link to post Share on other sites

I have often wondered if a wire brush is used for polishing. Link to post Share on other sites

From what I've read they don't detract from the technical grade (though could affect subjective eye appeal). They're also useful for determining authenticity and confirming varieties as die markers.
