I knew what this was when I saw it. I understand how most mint oddities happen. For the life of me, I cannot figure out the mechanics of how these occur.
It’s like a huge crack all the way around it’s hard to tell from picture I’m going to try and get better pics
Christopher there is no extra value. This is a deterioration issue that is common on Zlincolns. It is not a doubled die, and it doesn't look like one.
thanks pickin but I do clearly see two horizontal lines on the right side of the N maybe it’s not called a doubled die but don’t tell me it’s not there
in brief, Metal primarily flows outward (excluding the middle which flows up to fill the main image cavity). With the pressure of the outward flow the outer edges of the die wear faster .. thus the reason you see a lot of DDD like this. Remember the mint does NOT CARE about how the coin looks, they are after minting as many as possible, as fast as possible until the die totally dies. They reserve the nice looking stuff, and slower speeds/less die usage for Proof and other sets. The outside of the die also has much lettering too, which gives the metal more area to wear stuff quicker (more edges to wear out) - thus you see oddities in letters and sometimes rebound of the metal/die which creates fake doubling. Since the outside of the die wears faster you start getting partial "rings" forming around the outer edge of the die. In this case you can see the copper plate splitting too. Mike Diamond (several years ago) was investigating Ridge Rings as other world coin examples were creating Ridge Rings under different scenarios. Possibly due to hub/die manufacturing but those examples look kinda different.
Also if you look at extreme cases of die wear you have these examples: Die flow lines where the metal flow has etched away the flat surface of the fields, thus you end up with this which gets worse as you get close to the edge. here the "depth" of the letters have been worn away and the metal has elongated the letters. on the OPs coin you have this You may notice: on the right side where there is no lettering, there is no ridge ring. This is common as the metal has no letters to wear out the edges. So a ridge ring would normally form coming into this area from the top. On the bottom where the lower part of the bust is the metal mostly flows into the bust thus a low pressure zone. many times you'll see the "doubling" on the date/mm too as it has edges to wear out. the top and left contain most of the wear in this instance (with the IGWT letters). Maybe it is due to the die not exactly being totally flat too. unknown. But the pressure is wearing the edges then starts extending around until the pressure is relieved (bottom of bust). Remember the Hammer Die is the obverse .. it is the one hammering super fast. Thus the reason the reverse with the anvil die doesn't normally have ridge rings. So this is all die wear.
Thank you, Claw..... This one comment made the whole scenario crystal clear to me. I do get it now. I appreciate this.
I bet he would sell it if the price were right Sorry, had to say that, but let me add that I would be happy to find it also.
