It was taking a long time because the dates were smudged up on most.
Set scale to 48 grains, set up 2 plastic tubs, one for the 48 grains( 3.1 grams,95% copper ) and one for the rest of them.
This was a LOT FASTER than looking at dates..!!!
Just messing around....

Anybody remember that old DOS game called "SPOT" from 7up ? It looks just like these guys..!!
