I have this group of better date
IHC's. Unfortunately all but the 1879 have problems. I need a little help with value on these. I don't know if the pic is clear enough to read the dates so here they are:
Top Row........1866(corroded), 1868(environmental damage), 1874(countermarked)
Middle Row.....1875(corroded), 1876(bent)
Bottom Row.....1873(scratch), 1878(corroded, heated?), 1879
