hey, still haven't found my answer in other posts but i have been told that the 82 and 83 JFK halves are hard to find?? is that so?? due to something w/ circulation? i see online that everybody has a 1982 and 1983 proof of the JFK half dollar they are selling. i just found 1 1982 and 3 1983 JFK halves in my collection?? they are circulated around VG-8 to VG 10 do i have something here?
Not really, only those in MS quality will carry a demand or premium. The issue with JFK's and even the Washington quarters from 82 and 83 were that the mint didn't officially make these available in uncirculated condition, so all were put out in circulation, thus all got branded as being circulated. The only exception is each mint, P and D, both made souvenir sets available at each Mint from the gift shops that are actually uncirculated. But those are limited and demand premiums as it's reported only 10-20k (numbers might be off, I'm going by memory here) were actually made from each mint but most are unsure since they didn't keep track of the actual sets produced. All other uncirculated sets from these years were produced by 3rd party providers. I picked up both years P and D sets, I paid over $100 for each year to put with my uncirculated mint set collection. Also keep an eye out for the 87 Kennedy, it carries a slight premium because of low mintage numbers but it's not gonna make you a fortune and uncirculated mint sets still sell between the $5-$10 range.
Unless there is an obvious, and rare, error in the minting that actually occurred during the striking, nada. But it would have to be something never occurring before and/or seen before either.
