I suspect the first one is indeed a replica/copy of the Crusader-era coin. I know WRL produced replicas of this coin for sale in their historic coin packets. I suspect the odd littel "C" mark is the mintmark of the replica-maker.
The second one is indeed an Ottoman Turkish bronze coin, Constantinople mint, dated Accession 1255 Regnal Year 2 (AH 1256, or AD 1840). Which denomination I cannot say without an indicator of size.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
