Japanese coins for swap/purchase

Anyone who has old Japanese coins. I'd like to collect coins who preceed the Kan'ei Tsūhō coins.

I can provide coins from the period when the Kan'ei Tsuho was produced. However, prior to the production of the Kan'ei Tsuho, Chinese coins were imported into Japan, and since domestic coins are rare and expensive, it is difficult to help.

Thank you for replying Sigeichi, I believe I sent you a swap offer for a Japanese coin from the 1500's. Do you still have that coin? Any old japanese coin besides Kan'ei tsuho is fine because I have relatively enough of them. I'd like to hear from you!

Kind regards,

Ridvan Palit
