Not sure if you're talking about Flying Eagle cents or Large Cents. If it's Flying Eagle's I'd go to, in no specific order..... http://www.ldrcoins.com/ http://mesacoin.com/ http://www.indiancent.com/ http://www.thepennylady.com/ http://www.markfeldcoins.com/
I have an 1855 PCGS PF63 Pattern that will be in Bowers & Merena's Baltimore auction in November. Their online catalog should be up by the end of the month. http://www.bowersandmerena.com/
I believe that 1854 and 1855 were the patterns years for your description. Judd's book mentions that restrikes exist, so buy/sell with an expert or TPG authenticated. Charmy, does the label say which which metal yours is? They were striking so many different alloys leading to the Cu-Ni cent, I was wondering about yours. Jim
