FLYING EAGLE CENT PATTERN COMPOSITION TESTING

Rick Kay writes: "Iím SEM-EDX testing 1854 and 1855 large flying
eagle patterns to determine what the variations are in metallic
composition.  I am also studying die characteristics in an effort
to determine the timing of the production of the various Judd
numbers.  Finally, I am going to study the color, reflectivity and
other characteristics to figure out any trends.  Iíve tested over
20 so far and will be sending in another 30 or so in the next two
weeks.  Here are some questions I currently have:

"What is the range of compositions for oroide in 1854 and 1855?

"Is 90:10 thee same as 88:12 in C-N coins?

"For bronze, what is a reasonable variance from 95:5?  What about
percentage of Sn v. Zn?

"Information or leads on Mint or other records

"Is there any reference in Mint or other records to oreide
or oroide?"
