Welcome to CT Dustin. You will find out quite quickly that photos of your coins are pretty much mandatory here. If you need help on how to best post photos, please just ask. Missing designers initials are fairly common as the dies are polished and the raised letters are the first to be removed. I'm not a Kennedy person, but doubt it would fetch any premium.
Thanks for the reply. I'm asking because evidently some YouTube guys are making a big deal out of the no FG like they are worth money. I guess someone at the mint made a mistake and over polished some of the coins and polished of the fg initials. I went to eBay and there's several listing for these Kennedy coins but ZERO bids on any of the listings. I'm thinking YouTube guys are trying to make more content to up their ratings and subscribers.

I wouldn't get coin advice from youtube videos. I guess while you're looking, keep an eye out for the 74-D DDO too. https://www.pcgs.com/coinfacts/coin/1974-d-50c-doubled-die-obverse/96723
