Hussein Kamil Mint Error 5 Piastres ND (1916-17) XF40 PCGS, KM318. Full Brockage Error. An eye-catching error with an incuse mirrored image of the obverse where the reverse is typically placed. Very pleasingly preserved as well, with alternating cameo appearances on both sides. The first error of this magnitude that we've seen on this type.
Estimate: 2000-2500 USD
