Ferdinand VI gold Cob 4 Escudos 175(0)L-R, KM-A47, nice XF with strong details, the L mintmark and 75 of the date are very clear. The 4 Escudos is not known dated later than 1750 and thus the date is inferred despite the fact that the 0 is not on the flan. Rare and quite attractive.
Estimate: 4000.00-5000.00 USD
