Ok your own math doesn't add up. You said 78 mylars were aprox a pound and that pound would yield 12 to 15 grams of silver. So if we take 12grams and devide that by 78 mylars you get .15 grams of silver per mylar not .05 Also I went out back and weighed the mylars I had taken out from random keyboard and I get closer to 50 mylars per pound.
