New Year's Sale! Bunsei Koban gold coins were reportedly minted from the 2nd year to the 11th year of the Bunsei era (1819-1828). (From the Japan Numismatic Dealers Association materials). A replica reference item of this coin was in storage, so I am offering it for sale. - Material: Unknown (Possibly brass?) - Weight: Approximately 12.2g - Dimensions: Approximately 72mm x Approximately 39mm x Approximately 0.6mm - Stamp: Has a cursive "Bun" stamp on the back. - Condition: This is a stored item and has noticeable scratches on the back. Please refrain from purchasing if you are sensitive to imperfections or are looking for a brand new, unused item. Please allow for some error as this is an amateur measurement using a commercially available measuring device. This is just a replica reference item, but please consider it for your collection as it is currently very popular for good luck with money! Thank you for viewing.
