| I am actively researching die and metallic varieties of 1854 and 1855 large Flying Eagle pattern cents and have turned my efforts exclusively to this research. One important portion of this research is testing for metallic content via Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDX). This is non-invasive testing in which s-rays are shot at the coin, and the surface layer of the coin is "analyzed." My offer/request: I will deliver your coin to PCGS or NGC. They will crack out the coin and send it to a laboratory for testing. The coin (and results) will be sent back to PCGS or NGC. PCGS or NGC will re-slab the coin at the same grade as previously slabbed, with the composition and weight on the slab. I'll pay for the testing. If the coin is not already slabbed, I'll pay for slabbing fees to get the coin graded, in addition to paying for the testing. If you prefer that the previously unslabbed coin remain raw, I will take the coin to the lab myself. I can also send coins in other TPG slabs to PCGS or NGC for cross and testing. Timeframes (from time delivered to PCGS/NGC): PCGS-slabbed coins to PCGS for testing only--> up to 4 months NGC-slabbed coins to NGC for tetsting only--> up to 1.5 months Raw coins for testing only--> up to 1 month Raw (or other--TPG-slabbed) coins to PCGS for testing and slabbing--> up to 5 months Raw (or other-TPG-slabbed) coins to NGC for testing and slabbing--> up to 2.5 months email me at rkkay@rick-kay-rare-coins.com if you have questions or are interested. I am still available to help in any way I can, but no longer carry an inventory. Rick |
