I've just spent $20 on a truly horrible coin, but it filled my last gap in the series of French bronze 10 centime pieces (1852-1921) The 1878 K Bordeaux mint has a recorded mintage of 100,000, but probably the vast majority were dated 1877, and is the rarest of the series (Ok there is a very rare variety of 1897 - 3 known) much harder to find than the 1871 K (mintage 26,500) and catalogues at €150 on Good (B10) I tend to buy interesting coins by type these days, but at heart I guess I'm still the one trying to fill all the gaps in my Whitman folders
