In addition, when a coin's seal mark written in ink faded away, people brought it to an obanza (place to mint Oban) and the writing in Indian ink could be rewritten with the fee of three monme and five bu of silver, or one bu of gold after 1819.
また墨書が消えた場合、大判座へ持ち込み、銀三匁五分、文政2年（1819年）以降は金一分の手数料で書改めを受けた。
