1967 LMC Die Chip Or?

First time I've seen that one. I'm going to add the images to my educational files. Thanks for posting this.

I am not sure what these two raised blemishes are. I'd have to examine them under a microscope. They may represent tiny areas where the die face sank in (similar defects occur on recent Jefferson nickels on the sides of Monticello). That said, I have never seen a convincing case of abrasion doubling. All of the "iconic" cases published in the CherryPickers' Guide are examples of Die Deterioration Doubling. I debunked the category of abrasion doubling in a 2013 Collectors' Clearinghouse column in Coin World. I can't rule out abrasion doubling ever occurring; I've just never seen a bona fide case.

Extensive subsidence and polishing around the date area, as noted, resulted in some of the coin metal being pushed out from the 1 digit in the date. When the planchet was struck, some of the coin metal flowed out of the heavily-polished 1 digit area and into the sunken field directly adjacent, creating the appearance of a die chip. The 6 and 7 appear to have Strike Doubling to the east that may have been exacerbated by the heavily worn dies, allowing the planchet to "bounce" slightly when struck.

The heavy polishing lines (raised on the coin and incuse on the die) are a sign of a deteriorated die which was polished (abraded) and remained in service.

I would expect this defect on the 1 to be considered a strike artifact which occurred due to extensive repolishing and recutting of a very worn die, in line with Mr. Coop and E&V.

I see Mike Diamond. It will be up to Aziz_R, if he wants to send it to you or not. We'll see. :-)
