1974 Dime Error Raised R

if it is impressed into the coin it's some sort of vise job. If raised I have no idea.

Could be glue or something. Try soaking it in acetone.

The rim is flat/squished where the 'R' is and it's reversed.

That can't happen during the minting process.

Thanks all for weighing in, I'm new to errors and don't know a great deal about them. There has been a lot of back and forth over this coin on another site as well. I found it in a coin roll and have no idea of where it has been. I do find it odd that someone would go to the trouble of creating some sort of die to press a single R into the rim, circulate it and forty plus years later it ends up in my hands.

I'll try to get some better pictures put up later
