Pls post a picture so we know what you are referring to. What's a "re-entry"?

The only time I have seen "re-entry" used is in the space program. Are you referring to a counterfeit coin?  |

I'd be the first to buy a "heat shield" coin Jimmy. Can you say PMD?   . "We are poor little lambs...who have lost our way...Baa...Baa...Baa"

I think he means doubled die. A re-entry is stamp collecting terminology for a type of doubling.

Tunnioc yes you are correct. but in the old days re-entry was a word used to describe. a new variety that was done. when the master die was at its end. so the mint created a new master to finish a run of coins. when that happen the the new master die had some small little different from the oringinal master. similiar to stamps. right now I am reading alot of older coin books. one of the books stated these young people. know a days always trying to change collecting language, it struck me quit funny. have a great one

I think that Hans needed to bone up a little on the preparation of dies. By his definition, EVERY die would would have been "re-entered". It took 2-3 times to both harden the original and anneal(soften) the receiving die component. It makes no difference whether you are talking about the master or the hub or the working die .. it couldn't be done in one shot. Is the OP trying to describe hub-doubling?

While Hans Zoell was meticulous, reading his works it is obvious that he did not understand the nuances with die creation, and strike variations from the deterioration of dies.
If this was done to the master die, then such features would be transferred to all the working dies.

spp ottawa question. I want to try to explain this correctly. ok I have 2 coins. the question is if the obverse inscription is off by half a letter. this would be a new variety correct. see I have put together a computer program. I can check a coin in seconds. if there is the slights difference when using this program. to check coins you will see that so easy. see the program also applies plotting. the type of plotting I am talking about if you know anything about the pathfinders. then you know what I am talking about. ok for the pathfinders what I am using is called through the door up the stairs. so any of you that had been trainned to use that terminology. knows the accuracy is 100 percent. so if any part of a coin is not completely identical. you see it on the monitor instantly. meaning right down to a tiniest detail you can imagine

Therein lies the question - at what point does a change in the die become a variety? To put that in other words, how would this scanning method account for Die Deterioration? Die cracks, chipping of chrome plated dies, and other features can evolve on a die's surface simply from being used to the end of its meaningful life... coins struck by the same die at different stages of its like, will not be identical. Other factors, like Machine Doubling, come to mind... In my opinion - all of the above does not define a variety, much like a grease-fill die would not... a true variety, or difference, has to exist on the working dies.

SPP and I know a person, locally, that seems to be working on a very similar "electronic" method of precisely examining items ... in both cases they have applied it to coins during the tests. He is also a member of this forum. You two should get together and talk.

spp that no problem. what I have found so far are all true varieties. okiecoiner sure I would not mind a bite having a chat with this person. okiecoiner thank you for suggesting this. I have right now 10 solid new varieties.i went had a chat with a couple of dealers. they are more than willing to supply me even more coins. all I have to do is catalog theres for them before they are returned. oh and yes we have a little deal worked out. thank you both for your input.

Given that dies are designed on computers... I can imagine where your scanning might work is when there are changes in things like font styles, kerning and spacing sizes... that said, you still need two to produce more than one master punch (matrix) and master die, to then create the working punches (hubs) and dies.
