I get $30 (3 rolls) of halves about every month to look through. In my last 6 rolls.....nothing, but the previous roll acquisitions had at least 1 half (40% or 90%) in each roll on average. My best roll hunting was 2 yrs ago when I was going to New Mexico for my annual metal detecting of ghost towns. I pick up rolls of halves from small banks, thinking that older people are turning in their coinage for the paper stuff. I hit a bank (oh-oh, with Bushie's spy tactics, I should change the word 'hit') in Mountainair, New Mexico (Pop-1100) and picked up 3 rolls. Roll #1 and #2 = Zilch (0). Roll #3 had (11) 40% and (4) 90% halves (all J F K). Last yr I went through the same town, stopped at the same bank........"Sorry, we don't carry any halves anymore." With the 9 rolls I picked up on the trip last yr, I only found (3) 90% Kennedys (1964) in the 9 rolls.
Now I have a hunch that with the fiscal situation going on throughout the world, many people are going to begin to empty their coffee cans, piggy banks, and jars of their change to get a little extra loot (uh-oh, not a proper word - 'loot' - to go along with 'hitting a bank'.)
