That depends, if you like them, keep them. If you are not a fan of JFK's keep the nicest one, and spend the rest.
This roll bids at $20. It's easy enough to get bid for BU moderns but buyers don't want a lot of junk so unless it's a nice looking roll I'll spend it. This doesn't mean that it's not worth $20 just that it wouldn't be worth getting a bunch of stuff sent back because some of the coins were junk. This is a fairly easy roll for clads but it has decent demand since it's a Kennedy and so many were poorly made that fewer were set aside and many collectors are seeking upgrades. It might be the toughest clad Kennedy in nice MS-64 and MS-65 but higher grades aren't especially scarce relative other dates. It is found as a spectacular satiny gem with a clean shield in about every 180th mint set. Roll coins tend to be awful with few coins exceeding MS-60. Strikes are horrendous and with significant die wear. Marking is usually omnipresent. There is some pressure on supplies of this date by wholesalers. While there are hundreds of thousands available they are difficult to get to market when the price is only double face value. Demand just keeps ratcheting up and even a quadrupling of prices would not significantly increase the number coming onto the market. Most of the supply is a few rolls here and a few rolls there. There are still hundreds of thousands of mint sets but few are coming onto the market and buyers suck these up even before they get to the wholesale market now days. All these markets still surprise me in their ability to resist increasing prices. It is probably just a weak demand moreso than a large supply. This is evidenced by low prices even on the scarce and rare issues. I still believe these will become a mass market in the long run and demand will far outstrip supply. With tens of millions of Americans collecting clad rom pocket change it would seem inevitable that as they and the markets mature that demand for the older clads will increase substantially. There is no doubt that higher demand will show just how scarce many of these coins truly are.
