There are a lot of rolls of
Presidential dollars available. The two most prevalent ones seem to be wrapped in "US Mint" paper and in generic looking "N.E. String and Sons" paper. What's the difference? Do the coins get wrapped at the same time but simply get a different marking on it to make one set more collectible than the other?
I see a huge premium for US Mint rolls. I've been trying to get a 2007 John Adams P US Mint roll from
ebay and the winning bid is sometimes almost $2/coin! So I'm figuring there has to be something that's different.

Thanks!
