Multiple 60's Finds + Questionable Coins

Hello everyone! First post here but have been viewing the forum for a small while.

I'll cut to the chase, I've been collecting for about 2 years now, and have always collected 60's and 70's copper cents just for the fun of collecting them, but recently I learned more about varieties and errors and decided to take the day and look through my 60's collection of about 900 coins. I mainly used the PCGS website for the types of varieties.

Anyways, this post is partially to show my finds But also to ask for some validation on some coins I'm unsure about aswell.

Just a visual of the 900 coins! it's all 60's and 59's (59-69)


First and favorite find, here's a 1959-D/D/D RPM


Here's the full Obverse and Reverse



Next is I think a DDR on a 1966, I couldn't find anything online matching this kind of doubling(if it is doubling).




Next is one I'm curious about, a 1964 with possible doubling along "United States"


Finally, another unsure one, a 1968-D with what could be doubling next to the Monticello.


Other than those finds, I found a few cool grease strikes, and 7 "1969-D No FG's with floating roofs".

And that wraps it up! Please feel free to let me know if certain ones have doubling or not, and let me know if I'm incorrect with any of these coins, i'd love to know more! Thanks so much, and have a great day!
