[QUOTE="messydesk, post: 4686214, member: 1765"]There really isn't controversy as much as there is misunderstanding. Looking at the rest of the die for all three die pairs shows the same thing happening. With wear, the indistinct under-mint mark becomes more distinct. You need to look into the process of making a die (or 3) with a corrected mint mark. The wrong mint mark needs to be effaced and then overpunched with another. Effacing the wrong mint mark does not mean simply polishing it off the die. It is recessed in the die and polishing it off would mean removing a lot of surrounding detail and/or leaving a dish on the die (hump on the coin) where the wrong mint mark was. Punching the correct mint mark there would make it a high point of the coin. What has to be done is the wrong mint mark needs to be somewhat filled, then repunched, then polished a bit, leaving little to no trace. Punching the new mint mark will also raise a little metal, pushing it into the old one, filling it a little. Now put the dies into use. All three will work fine provided erasing the old mint mark was done well. If it wasn't, the repair will fail in the form of a die chip bounded by the weak border between the repair and the original mint mark. Another thing to consider is that as a die wears, features don't spontaneously become filled in. Die cracks don't close, die chips don't go away.[/QUOTE]
