1 Cash - Qixiang Tongbao, Boo-yuwan

Qixiang was the reign title chosen by the young Zaichun following the death of the Xianfeng Emperor in August 1861 — but it was used for barely four months. A regency coup in November of that year, orchestrated in part by Empress Dowager Cixi, overthrew the eight-regent council and replaced the reign title with Tongzhi. Coins struck under the Qixiang title were immediately withdrawn, making the production window extraordinarily narrow.

Boo-yuwan is the romanization of the Board of Revenue mint in Beijing. Surviving Qixiang issues from any mint are scarce; this particular board attribution keeps it firmly within the documented series.
