I'm an old man but, now I'm confused too. Finally hit 300? I looked at attachment 776846 and I saw three dime rolls and the seated liberty which I would count as hitting 151. Are you using some new form of math that I am not aware of? I like keeping my dimes in plastic holders that I have espically the square ones that fit just right into the cigar box I keep them in. I get them falling out of those clear plastic wrappers too often. Good job on the dimes and nice seated one.
On second glance they do seem to look bigger than a normal fifty roll. I've never seen any 10 dollar rolls of dimes before but there does appear to be more in those when I looked again.
