I am currently researching a paper on the mintage and history of precious metal rounds, including the world-renowned Engelhard American Prospector series.
I am in need of information regarding the history (development, design), and mintage-numbers of the Prospector series.
Are you able to provide any details on the Prospector series? Do you know of any prior publications (books or articles) which offer details?
My paper is purely for non-profit, academic research only, to be freely shared with the numismatic community upon completion.
I very much appreciate any information you can help me with. Thank you very much!
Have you tried contacting Engelhard directly? Earliest dated Prospectors I have are 1982. I have other rounds dating back into the early 1970s, but none from the 1960s.
Here in Wisconsin, we have some of the highest property and gasoline taxes in the US. We're squeezed so much, I have to make my daughter wear penny boxes for shoes. At least she has an endless supply.
