Question: Are NIFC Half Dollars Worth Getting?

75 cents per coin sounds very reasonable (pending condition) if you're looking to fill a JFK album....What the range of years ?

So the question/answer you/we are looking for is, when did the JFK halves became NIFC ?( From memory I might say mid 80's )That I can not say for sure but maybe google has it ?

edited: here's what I got from google.....Half dollars not intended for circulation, such as proof coins and those minted with dates 2002 through 2020 occasionally enter circulation; these issues are sometimes found through coin roll hunting by collectors, being referred to as NIFCs (from "Not Intended for Circulation").
So if those late 90's are UNC...not a bad deal ( @ 75¢ ) in my eyes. If you're filling an album

I agree with those who said they are worth it if you are building a Kennedy half collection. And that 75¢ is a reasonable price. A better price than they sold for from the US Mint! Aside from filling gaps in a collection, I couldn't say.
If you're hoping to flip them...ehhh, if they're BU, maybe, but there's not much margin. But a person with a few pesky empty holes might pay 2-3 dollars, shipping included.

I think I can clarify the years of the recent NIFC Kennedys. They were made only for collectors in the years 1970, 1987, and from 2002 to 2020. Beginning in 2021 they were returned to circulating coin status.

Why pay 75¢ for a 50¢ coin - that's my take on clad Kennedy halves. Even though they are so called "NIFC" you still find them when roll searching.
