You have some nice coins...looks like you have taken your time to get the top examples...
From what I can see the FE is VF or better...kinda hard to really see due to quality of print reflection...(originally called a nickle)
I have a rather broad collection of FE's...which I think are probably the most beautiful of designed coins...
FE's are always a good addition to any collection...in my opinion, always buy the best you can afford...many times a VF or better costs the same as junk...
Just as a side comment, I have a well worn FE that is suspected to be a 1856...one of these days I'll get up the guts to get the date to appear...its kinda fun beleiving its real though...why break the bubble
