| J-170 or J-171? Possibly Neither. (1855 80%/20% and 60%/40% copper/nickel Four-Leaf LFEs) Although the 9th Edition of the Judd book refers to both J-170 and J-171 as low R7 (7-12 believed to exist), it is very possible, maybe even probable, that neither exists. My research is the third time patterns labelled "J-170" and "J-171" have been X-Ray tested, to my knowledge. On no occasion did any test out as 80% copper and 20% nickel or 60% copper and 40% nickel. All the coins have tested out at 90% copper and 10% nickel (J-170A) or at some combination of copper, nickel and zinc (German Silver: J-171A). The coin pictured contains approximately 68% copper, 17% nickel and 15% zinc, making it a J-171A. It was sold as "J-170/171" by a major auction house. |
