I probably should have added this to the old thread but can't find it now (sorry) The famous 1887 sale by Rollin & Feuardent of the Ponton D'Amercourt sale (Roman & Byzantine gold portion) is now listed on the Coryssa test server complete with prices realized: http://coinvac.crabdance.com/index....period/all/list_order/date/list_order_dir/asc Coming up with accurate pricing was a bit of a challenge. The sale was settled in French Francs and I couldn't find any direct Franc-to-Dollar conversion rate from that far back but managed to work it out from various sources based on comparative labor rates to 1 Franc = $5.25. The rate based on the buying power of gold came to a multiple of 5.15 so either way close enough. Obviously, the prices shown are contemporary. For a good idea of equivalent in 2019 dollars click on the Adjust for Inflation button on the upper left. It is, to me at least, amazing that after over 130 years the prices have remained so stable. Most of the cheaper ones would seem overpriced in today's market but the rare "highlight" lots would feel right at home in your average NAC or Nomos of nowadays. Enjoy! Rasiel
Interesting overview list of such old auction results , thanks for sharing Rasiel. 2 comments the coins look silver due to the b/w images. perhaps an adjustment in color ? And I think the US - French Franc is wrong. Here are 2 US gold coins, the Bickford and the Stella which show a ratio of 20 US cents for 1 French Franc.
Oh wow! I did goof up the price multiplier. Thank you for correcting me. I just took care of this. Rasiel
