Watch List notes:

Mexico City, Mexico, proof copper pattern 10 pesos (gold), 1869C, NGC PF 63+ BN, finest and only known example in NGC census, very rare. KM-Pn118. With rainbow toning over choice luster, this is more properly considered a specimen, as the details are sharp, the fields show strong die-polish and the rims are raised, devoid of marks or wear in any case and with very nice eye appeal. NGC #4660486-002.
