1969 S 5cent, Rim Fin Or Small Cuds?

If you see the rim on that area, it is not a Cud. It appears to me that it is something struck onto the coin, or post added to the coin later after the strike. In order to be a Cud, the outside edge of the die would be missing. As long as you see the rim on that area, it is still in tact.

Note the missing outside edge of the right? That is a Cud. On the front image of the left is a simulation of what a rim Cud would look like.

This is a small reverse Cud. Note how the metal is taller than the rim? That is because of the void that is now there on the missing part of the die. Your coin looks nothing like this. It is just a struck though are a re-attached lamination. Note on your coin, the rim is normal in height. Just something attached there that you are seeing.

Well it may have moved from this coin to a new location. Note how the top of the device is not shaping to the device. That tells me it wasn't there during the strike. It would be struck flat onto that device if it were.

looks like rim fins to me

Not sure how to tell if it's struck through retained foil. So it's either nothing or it's something lol were narrowing it down:p
