Guatemala (Central American Republic), 8 reales, 1841/37 MA, NGC MS 60. KM-4. Choice strike with no weakness or flaws except some weak parts on rims (as made), lightly rainbow toned over luster and faint surface hairlines, erroneously listed as "top pop" at NGC due to mistaken attribution to new listing "1841/7" instead of 1841/37 (the 4/3 not really present but expectedly so).
Estimate: 800 - 1200 USD
