Hey ya,
I went through two batchs of halves with nothing, So I bought a 2 boxes of pennies. I got about 12 dollars worth of pre 1982 95% copper, about 15 wheaties, one from 1910, and the rest I set aside to put towards my new hopefully box of halves. I can get discouraged just trying to save up for buying one box of halves. So I save up till I can get 1 roll or 8 rolls. Finally out of 8 rolls from one bank, I got 3X40% halves. Its not much after gas and the face value of the coins but hey, its a start and that was a yeah! moment for me. I could have quit after driving 50 miles, using a quarter tank of gas to get 80 dollars worth of skunk halves. but I tried something else, pennies, till I found those wheaties and that cheered me enough to go back to halves. If you are going to let one setback bring you down far enough that you don't want to open coin rolls again, I would get out of the hobby. Once its no more fun, its not worth doing.
Sincerely, GarouLady
