wondering if you folks , presort' your coin by type of wrapper.
i then open 10.00 increments into cottage cheese bowls. and weight the 1,000 coins
theoretically 1,000 zincs would be 2500 grams, with pure cu being 3100
in doing a many sets of 10.00..... i have arrived at an average in tucson of 2610 grs. this is for bank rolled as the cwr is too variable.
i do end up with 'highs and lows' by sorting the wrappers though. like the 3050 gr lot i got yesterday. i only saw a few zincs and no wheats as i opened the paper rolls.
on the other hand i got a 2525 last month. there were only 7 cu, and 12 82's. ie, sorted by someone else already
