Stamped Chinese characters on a banknote I cannot translate, it would be great if you guys could. It's a stamp on a Hong Kong banknote from 1941.
Read right to left, top to bottom.

富行揀選
樣券

富行 was short for 雲南富滇銀行 (The Yunnan &quot;Fu-Tien&quot; Bank), 揀選 meant &quot;select, pick&quot;.
樣券 means &quot;banknote sample&quot;.
