The 1929/1-B Great Britain Hong Kong Silver Trade Dollar is a rare overdate coin struck in Bombay. The overdate occurs when the "1" from the earlier 1921 die remains visible beneath the "9" in the 1929 date.

Featuring Britannia on the obverse and Chinese characters on the reverse, it bridges British colonial influence and Asian markets. Struck in Bombay (indicated by the "B"), its intricate design and historical significance make it a treasured relic of global trade history, reflecting economic and cultural exchanges during the height of imperial trade.
