Republic Sun Yat-sen "Memento" Dollar ND (1927) AU Details (Cleaning) PCGS, L&M-56, KM-Y318a. Six-pointed stars variety. An interesting example in the popular 'Memento' series which features a scarce misspelling of 'REPUBLIO' in the reverse legend. The surfaces, once cleaned, are now starting to re-tone.
