Watch List notes:

Potosi, Bolivia, cob 1/4 real, Philip III, no assayer, shield around castle, large lion without shield, very rare. KM-unl; Cal-unl. 0.79 gram. Darkly toned AVF with hole near edge (but not salvaged like most), full (large) lion without shield and nearly full (off-center) castle in shield with nearly full crown above, the latter linked to Philip III by style, hence very late for 1/4R since some records indicate that 1/4R ceased after Philip II.
