Are they unsearched?! End toner rainbow l@@k. Just kidding, as a nickel lover I would be all over that.
One man's Gem BU is another man's VF. Redbook says $14 for MS-60. Personally I would pass. I have bought "Gem BU" rolls before and they were anything but "Gem BU". They had all been dipped and were very shiny, but, very circulated. Here is a picture of a roll I bought along with the best coin out of the roll. I think I paid less than $10 for the roll. It was still overpriced.
Wholesale is $275 right now. I have five rolls that are in those old style tubes that have shrunk so much that the coins can only be removed by ruining the tube. I opened one about 20 years ago and they were beautifully preserved. I would LOVE to get $500 a roil!
Pass at $10 -12 retail these days you ll never make any profit. I still have about 15 laying around here.
