yes Accumulator's post is mind boggling but i hope to understand one day, i love that one penny coin with the two colours is very pretty I presume you refer to the bi-metallic model penny in my avatar. This coin is fairly common, having been produced in great quantities by Joseph Moore as an alternative to the pre-1860 large copper pennies. His concept was that the intrinsic value of the metal centre allowed for a much smaller coin. Despite being popular with the public, they were never officially adopted and in 1860 the Royal Mint produced the now famous 'bun head' bronze penny instead. The particular coin in my avatar is extremely rare, being one of only 4 known which display a date (1844). Wow thats really exciting known you have that coin i will have to look out for some of the not so rare ones to add to my new collection, thank you for all your addvice :-)
