Supposedly the last year that Chinese merchants chop marked coins was 1935 when China abandoned the silver standard. This is my latest, from early in the 20th century: United States Philippines peso 1903-S with chop marks Who has the Chinese chop marked silver coin with the latest date?
My latest, well my only is a Mexican 8 reales dated 1782 - but it has a lot of chopmarks. Back when I bought it I paid then melt value which was about $5.
