Proof Sets | World Coin Book

COIN — LEGAL TENDER

Coin identity

A monetary object linked to the existing circulation generation or commemorative issue. A set appearance never creates a duplicate coin type.

MEDAL — NOT LEGAL TENDER

Official medal

A Japan Mint-struck non-coin object with no denomination. Medal condition is recorded separately from coin condition.

PRODUCT

Commercial set

The bundle has its own product code, contents, sale channel, price, and issue quantity; it is not itself legal tender.

PACKAGING

Holder and documents

Cases, folders, capsules, booklets, and certificates belong to the product. Their condition does not assign a coin grade.

Normalized products

Official product register

A dash means the cited official source has not yet supplied a normalized historical value; it never means zero.

Price and quantity boundary

Issue price is the original Japan Mint sale price, not current market value. Product issue quantity is not coin mintage. Unknown values remain unavailable.
