Another irritating item on the Safari is instead of getting the usual
[size=large]35[/size] on a penny, you'll occasionally get a [size=large]36[/size], sometimes a [size=large]37[/size] and to really confuse you, sometimes a
[size=large]38??????:[/size]stars: I understand the different numbers come from different metal compositions including encrusted iron or different metal particles but I have always wondered a penny is a penny is a penny and they have never differed in size (at least for a few decades) so why the difference in numbers and whats more, a graduating higher tone almost fooling you that it's a Quarter coin that's under your coil? With a penny thats accumulated a lot of salts on a beach, this problem is more prevelant.
I may be answering my own question here but I decided to post the following to smooth over my (and other detectorist's) frustrations on this subject! and which might either shed light on this or make this question even more complicated!!!!
Penny metal compositions through the years:
1793-1796.....100% copper
1796-1857.....100% copper
1856-1864.......88% copper, 12% nickel
1864-1942.......95% copper, 5% tin & zinc
1943...............Zinc coated steel (also known as the steel cent)
1944-1946.......95% copper, 5% zinc
1946-1962.......95% copper, 5% tin & zinc
1962-1981.......95% copper, 5% zinc
1982................Varies, 95% copper, 5% zinc, or 97.5% zinc, 2.5% copper.
1983 to present...97.5% zinc, 2.5% copper (core: 99.2% zinc, 0.8% copper, pure copper plating.
In honor of the Lincoln cent's 100th anniversary special 2009 cents were minted for collectors in the same composition as the 1909 coins.
So.........................can we blame the guy's at the US Mint for fooling around with the metal make up of the humble cent? LOL
