Context
Historical and monetary setting
Postwar coinage began with continued low-value emergency issues and brass made from mixed military scrap. New yen denominations then appeared in stages; sen currency remained legally relevant until the 1953 adjustment law ended sub-yen use.
Identification
How to classify the object
Separate surrender bridge issues from the predecessor types of current denominations, and keep production start distinct from legal issue start.
