I was E-Mailed by a friend who knows everything about silver strikes that there was more total silver than I put on my first post. The 2 $7.00 strikes that I listed as having 0.60 after weighing are 20 grams each which is 0.70 oz's each & I was told the $20.00 Hard Rock is 0.75 oz's not 0.60. So there are 0.35 oz's more than which brings the total to 8.81 ounces. Thanks Ray
