Japan 500 Yen Bicolor Clad Coin

Context

History and monetary setting

The denomination began with a 1982–1999 cupronickel coin and continued with a 2000–2021 nickel-brass coin. Both older types remain valid in use, while the bicolor clad generation is currently issued.

Attribution

How to identify the type

Confirm the two-color structure, paulownia obverse, bamboo and tachibana reverse, 7.1 gram standard, and alternating-pitch helical edge. The three regular generations share a 26.5 mm diameter, so diameter alone is insufficient.

Collecting

What to record

Catalog the 1982 cupronickel, 2000 nickel-brass, and 2021 bicolor clad designs separately. Security features are identification aids, but suspected counterfeits require expert in-hand examination.

Design and symbolism

What the motifs communicate

Paulownia, bamboo, and tachibana persist while metal structure, edge treatment, and security features evolve.

Collecting

How to organize the series

Catalog the 1982, 2000, and 2021 generations separately. The three share 26.5 mm diameter, so metal, mass, edge, color structure, and security features are decisive.

Grading

Surface and wear checkpoints

Separate circulation wear from damage to the edge and security elements; prooflike brightness is not proof manufacture without the correct mint-product context.

Authentication

Generation-correct diagnostics

Use generation-correct 7.2/7.0/7.1 g mass, edge, alloy or bicolor structure, latent images, micro-detail, and official-design alignment. Suspected counterfeits need expert in-hand review.

Major diagnostics and varieties

1982, 2000, and 2021 security generationssecurity generation

Check alloy or bicolor structure, generation-correct mass, edge, latent image, microdots or microlettering, and irregular helical ridges.
