1  HOME SWEET HOME / Crafty Housewares: Completed Projects: Reconstructed / Re: Penny (too many) for your thoughts?? on: July 10, 2012 08:06:50 AM
I got curious about the 1982 thing too... so I went to wikipedia (http://en.wikipedia.org/wiki/Penny_%28United_States_coin%29)! it appears that was when the mix of metals used was sometimes changed:

Years    Material
17931857    100% copper
18571864    88% copper, 12% nickel (also known as NS-12)
18641942 19461962    bronze (95% copper, 5% tin and zinc)
1943    zinc-coated steel (also known as 1943 steel cent)
19441946    brass (95% copper, 5% zinc)
19621981    brass (95% copper, 5% zinc)
1982    varies, (95% copper, 5% zinc) or (97.5% zinc, 2.5% copper)[5]
1983present    97.5% zinc, 2.5% copper (core: 99.2% zinc, 0.8% copper; plating: pure copper)[6]

I'd imagine that the change to the mix of metals would also affect the appearance of the pennies, so asking for pre-1982 probably allowed for a more consistent look.

it really was a great idea you had here though! and it looks fabulous!
