My purpose for looking for error coins are to hopefully find mint errors, so yes it is my hope that every coin i show is a mint error or else i wouldn't do this. Clawcoins. As it pertains to the mint i thought blebs which are caused by a pitted die. I never saw any examples of a bleb. Post mint i thought maybe sand blasted, but it would of been more damage.
blebs are die erosion pits sometimes from the decarbonization of the die steel. Blebs are normally surrounded by (a) die wear identifiers such as (i) radial flow lines, (ii) orange peel texture and (iii) all the other stuff related to die deterioration. They also are usually also found on the (b) flat fields. Your spots are all over the place, also, there are no die wear identifiers surrounding them all. I'm actually impressed you've heard of blebs.
They look like stains. If the die was pitted the resulting coin would have raised areas. None of the spots look raised. You can find this on coins from the early 1800's when rusted dies were used occasionally, but modern production and storage procedures eliminated this defects
I thought it was strange that the defect didn't affect the rim. These are not stains. It's a lot of tiny chips out of the surface. The surface of a worn die will sometimes become pitted, possibly as a result of decarburization of the die steel. These pits are expressed on the coin as low, flat elevations with relatively soft, irregular margins. Blebs are usually surrounded by obvious signs of die wear, such as radial flow lines or an orange peel texture. Blebs are usually found in the field(coin world). The phrase"usually found in the field, meaning not limited too, had me thinking it could be blebs.
So blebs are made when the coin was being made? The "orange peel" description? And how often does this happen?
