These are beautiful scarce FDOI examples of this anniversary coin handled carefully after minting! I think ANACS got the grades spot on but please study the pictures to determine the grade and value for yourself, remembering that there are some small flaws in the plastic of the slab itself.
Greysheet CPG on the regular Philadelphia issue is $162 and the Denver issue $260. There is no category for the First day issues, I would think they are worth a little more. Two Philadelphia mint examples of this grade brought $109 & $168 ea. at large reputable coin auctions juat last year. There are no recent documented auction sales of the Denver issue but four of them sold back in 2017 at different auctions from $141-$306. there is no way to determine if any of these sales were first day issues or not.
