Stopped by my supply bank Thursday morning and picked up my usual Customer wrapper pennies from my favorite vault teller. I wound up with all she had- 4 boxes. Box 1 contained 1861 copper out of 2500. 74.4%. The newest cent was a 1986. Box 2 had 2149 copper for 86%. 36 of the 50 rolls were solid copper by weight. The newest cent was a 1985. Box 3 had 2436 copper out of 2500, 97.4%, 46 of the rolls were solid copper. The newest cent was a 1984. Box 4 was the best of all. 45 of the rolls were not CWR's at all. They were coin company wrapped rolls containing all 1978 and 1979 on the ends. Each roll weighed out to be solid copper. Most of the wrappers were from Brandt, Inc Watertwon, Wis. and the others were from Brinks. The other 5 rolls were modern day CWR's. Got 8 wheats so far, one was a 1943 steel. I haven't searched 82 of the rolls yet because they were solid copper by weight. It's a blast hand searching copper rolls just using a scale. I'll post a picture if I ever figure out how.
