1946 P Roosevelt dimes that have blistering and heavy polishing marks.

[Off Center]

Hello, I came across six 1946 P Roosevelt dimes from a bu roll that have blistering and heavy polishing lines on the obv and heavy polishing lines on the rev. I came across something similar while VAM hunting a few years ago. It was attributed to rusted/pitted dies. Could this be a product of the same die damage? Thanks.

most likely esp in light of all the polishing lines on this coin.

polishing lines and dots like this doesn't always mean rusty dies as there could be and probably are a few diff things to cause this effect but normally when you see super strong polishing lines and some other event, rust/pitting, clashing etc the 2 events are related and even if said main cause is mostly/completely polished away, it tells you that something(s) did happen and said events could have even happneed more than once.

nice pics.

diffused lighting? or perhaps some type of ikea light or flourescent?

In my opinion, I think it's just an abraded die. Like occnumis2021 stated it could have been an overzealous mint worker or, they did away with a heavy clash.

When I was conversing with Fred Weinberg, he had sent a large selection of wax caps that the US Mint workers created. They create the working dies and then cover the dies with wax in order to prevent dust, rust and debris from violating the working dies. I believe the rusty dies happen less than the late 1800s, but it may still happen occasionally.

To show the lighting on the abraded die better I believe the lighting should be on the east and/or west side of the coin. Lighting can be the #1 pain to master if one is looking for that very good photograph.

thanks for the reminder about the wax caps.

here is the page the OP needs about his coin. (more than you want probably lol)
