Progressive, Indirect die transfer: A form of die deterioration for those not checking the link. https://www.error-ref.com/progressive-indirect-design-transfer/
Dagnabit, you guys have to stop educating me. I've read all of Wexler's but can't remember everything, and this was one I plum forgot. Thanks for the post and link.
Lol @Mountain Man, I knew it because I've seen it a lot in other groups I am in, took me a bit to remember what it was called, but I knew it was in error-ref
The design on the obverse of the coin can have an effect on the way the luster on the reverse will form in different areas. That indirect design transfer plays a big roll in the luster shadowing of the reverse. This is one of the better coins to show what I am describing. The ball of Abe's head on the bottom and the 'V' of his bust on the top. Due to different pressures on different sections of the design the luster shows a ghosting of the obverse design. I think it show up better on wheat cents than it does on a memorial.
Idk about that 69 's had a lot of polish lines,and had carbon spots at times... plus the design and strike were different. 69's a flater look
My favorite years for memorial cents 61,62,& 63 esspecially the proofs the color and wet look has never been reproduced. That wet look copper just said bling.
I don't know......must have 'rabittitus'. I ain't seeing anything like what you guys are seeing........
