Historical and monetary setting

The official table notes manufacture beginning in 1951 and issue beginning in 1953. The Phoenix Hall design continued when the edge changed in 1959.

Identification

Confirm the Byōdō-in Phoenix Hall, 23.5 mm diameter, 4.5 g mass, and whether the edge is reeded or plain.

Evidence boundary

The unissued 1950 nickel-silver 10 yen is a separate evidence-gated object.
