What coin or series has the least amount of doctored coins?

Without doing any research I am going to go with GSA dollars, what is your thoughts? Probably find out in 20 minutes all the GSA dollars were dipped. Lol

My butcher sold me a cured ham. I told him I wanted one that had never been sick.
Roosevelt dimes.
Three Cent Nickel
Hobo Nickels. That would be a doctored doctored coin.
Shield nickels. I don't recall seeing many that had been worked on when I actively collected them ... but then that was almost 20 years ago. They aren't a popular series and are probably ignored by both coin collectors and coin doctors.
Coin doctors will gravitate to the most popular series and do their magic - be that tarnish, tooling or tampering... of course, in their spare time, they may dabble in other less collected areas... to satisfy the apparent insatiable appetite for tarnish or slip in the occasional fake rarity. Cheers, RickO
I stole that and posted it on the dreaded OFR.

Any coin dated 2017.

Based on the fugliness we have seen, I think the instructions might have been
1) Dump that canvas bag on the table.
2) When you push the round metal thing into the black plastic thing, make sure the side with the lady is up
3) Don't lick your thumbs

Registry coins are popular and the manhunt for these rarities never cease. Any coin that would garner additional levitation amoung the asstute would warrant exposure to the seedy side of hyped up docctoring. Careful and easy does it.
Morgans seem fairly consistent to me as do Franklins, although I've seen exceptions, of course.
Sometimes, it’s better to be LUCKY than good. 🍀 🍺👍
