sorry in advance for the crappy picture, I will post more when I get the coin in hand, if I am reading it correctly I come up with: _?_ yung tung pao cant find a reference to the top symbol, and cant find anything with yung as the second to cross reference. also, if anyone would care to comment on the split in the planchet I am all ears (i dont know if this is a cast coin and therefore a casting error or a struck coin and something that happened when the coin was struck or possibly even PMD). i know there is a collector market for US and canadian error coins, is there a market for these older types? (ive seen a lot of these chinese coins but none with a split like this) thankyou  |

This is a Japanese cash coin- Tem-po Tsu-ho (top-bottom-right-left), from the Ashio mint, Cr 1-9 in Krause 1700's catalogue. There it is dated 1741.(The mint mark is sideways, it should be at the top. Jones lists it as the large characters variety of 1741, made of copper.
Splits are a normal part of cast coinage- these were made in sand mould, with the master pressed into each side, the coins connected (hence the sprue on the Tao Kuang issue on this forum. The two moulds were bound together, and the molten metal poured into them. The coins were then broken off the "money tree", a square stick run through their middle, and the rims usually filed smooth- obverse, reverse, inner and outer. If the sand moved during the casting process, you would get a void. The coins could be remelted, and cast again, or released.

This is a 寬永e€šå¯¶ Kan Ei Tsu Ho not Tempo. Ashio, Shimotsuke Province, 1741-45. May I modestly suggest my new book "Early Japanese Coins", which is the latest on the subject. Available from authorsonline.co.uk, or Amazon. This coin is 4.201. David Hartill |

I am getting sloppy- too busy, and relying on my fading memory. You are absolutely correct in the attribution.
