How? The lamination is in the planchet and while it may not show at minting, it is still there. Right?
Yes a coin can be dated by a die marker if there is a obvious identical die marker on record. I have a lot of error coins where two different types of errors have been confirmed as being from the same die . The die first had a major clash and then the mint workers ground and polished the clash marks off creating another awesome error by removing too much detail off the die. This was confirmed from die markers on the obverse side of the coins. The die clash ones are really scarce because it is too easy seen and the mint workers probably seen it quick and polished it off the die.
Thank you very much for understanding my question and answering it in such an intelligent and well informed fashion!! I very much appreciate any opportunity to learn and I understand my questions will sometimes seem dumb to those in the know. Thanks again!!
I know how hard it is when someone is just starting out learning about error and variety coins, I was there at one time. It takes a long time and you just have to keep learning. I have been at it for near to 50 years and still see new things.
Yes, it does take sometimes moisture changes and environmental conditions, but yes the lamination does not magically appear.
sometimes the coin's environment can cause the bad mixture to start delaminating after it left the Mint. I know people who put coins in a freezer to further things like small planchet cracks and laminations hoping to induce even greater cracks and laminations.
