## Positioning among the Four Types of Chōgin in the Hōei Period

During the Hōei period, four types of chōgin were issued over just five years from Hōei 3 (1706) to Shōtoku 1 (1711), with a gradual reduction in silver purity.

| Name | Mint Year | Silver Purity |
|---|---|---|
| Hōei Nituho Chōgin | Hōei 3 (1706) | 50% |
| Hōei Eiji Chōgin | Hōei 7 (1710) | 40% |
| Hōei Mituho Chōgin | Hōei 7 (1710) | 32% |
| Hōei Yotuho Chōgin | Shōtoku 1 (1711) | 20% |

The Hōei Mituho Chōgin covered on this page has a silver purity of 32%. The others are Hōei Nituho Chōgin (50%), Hōei Eiji Chōgin (40%), and Hōei Yotuho Chōgin (20%). **When collectively referred to as "Hōei Chōgin", purities might be confused**.

For the overall history, see [Hōei Chōgin (General Theory)](/coinpedia/edo-silver-009-hoei-chogin).

## Identification and Precautions

Called Mituho due to three occurrences of the kanji "宝". The chōgin of the Hōei period have a similar "namako shape" appearance, and **the type cannot be determined without checking the mark**.

As silver purity decreases, the copper ratio increases, resulting in a darker surface tone and a tendency to develop tarnish or verdigris over time. However, changes also vary significantly depending on storage conditions, so type cannot be determined by tone alone.

Weighed silver currency lacks a fixed standard, and individual differences are assumed, making it difficult to ascertain type by weight. For primary verification of authenticity, see [How to Identify Counterfeits](/guide/fake-detection).
