I'm a long-time coin collector, and about 6 months ago starting 'hoarding' copper cents. Where I work there are 9 different bank branches where I can easily stop by sometime during the day and get two rolls of pennies. No one seems to care if you have an account with the bank when you are asking for just 2 rolls of pennies. I'll spend about 5 minutes each night hand sorting them ... which is about all I have time for!
I thought I was pretty big time until I came accross this website a couple weeks ago. 25k-50k pennies/wk sounds like a full time job even with a machine!
Anyway, here's what I've found so far:
1) Here in NJ I probably average about 30% copper
2) Haven't found much of anything from a numismatic perspective. I guess my best find was a 1947 Canadien in nice condition. Maybe I'd do better if I looked for errors, but I just don't have that kind of time.
3) Probably get about 1 wheatie every 150 pennies or so ... they are almost always from the 1950's. I can probably count on one hand the number of pre-1940 pennies. Canadiens are probably about the same percentage .... one every 150 pennies or so.
I imagine a scenario like this ... in the next 5 years or so copper prices push $7-8/lb. It'll probably still be illegal to melt them, but maybe I'll be able to sell reliably for $4-5/lb. Anything more than that would be gravy. In a hyper-inflation / end-of-days scenario I have doubts about whether a copper hoard will be of much value, but I don't think I'll have enough of a stash to make much of a difference anyway.
Anyway, it's interesting to read what other people are doing and finding, good luck to everyone sorting out there!
