1967 Lincoln possible double on date?

I only have these pics for now but looks like doubling on the date, specifically the 67. Any thoughts? Thanks.

Yeah but 67 is a really thick most of the sixties years of thick for some reason I see the same thing

Galen 59 That was not me that replied to your post ! Thanks for your opinion though!

 

In 1967 , they were using a double squeeze hubbing process to produce the dies, and since the die had to be removed to be annealed to soften it a little so the hub could produce a deeper impression. When returning the treated die for second squeezing, if there was not identical placement, the 2 impressions would both be visible, but the minor impression is going to be the same or close in height. If it is perhaps a tiny amount less, it will still be rounded and raised. This results in a true doubled die.

In the case where the die is exact, and is being pressed into the planchet to make a coin, the action is ( for several possible reasons) not exact in maintaining location ( loose in the press die holder for example) it can cause a smaller flattened edge on the devices of the coin. If chatter occurs, this effect may be on different levels. etc. This is not true doubling, it is Mechanical Doubling or Mechanical Doubling Damage.

And I will not even discuss single squeeze theory as actual die doubling.

Several references ( I recommend Wexler and Flynn's Authoritative Reference on Lincoln Cents ( 2nd ed. ) ) are invaluable if one desires to collect in this area.

 

Thanks Desertgem for taking the time to explain that in detail it's much appreciated !
