Chinese cash help! [solved]

I've never identified any of these cash coins, and I'd love to know where to start.  Here's what I got for $0.25 at a coin shop:





Is it real, is it fake, is it worth a million?  Especially if SmartOne is around, I could use a lesson or two on cash.

Good deal.

25c seems good for this coin, as they are common, although old.

It's a Chien-lung 1 Cash from Boo-yuwan. This variant is typically smaller than other cash coins of the era and the yuwan on the reverse (the right character) is flat instead of curved.

Many thanks!  I guess unlike Japanese coins, learning how to date and attribute cash is going to be harder.  I might actually get into it!

I would beg to differ.

First of all, you're welcome. I instantly recognized the coin as soon as I saw it; in fact, it's right in front of me.

With Japanese coins, it's much harder to find out when they were issued because they all have the same era date 寛永 and 天保通宝 for 1 and 100 mon, respectively. Whenever there is a character on the reverse, such as 文 or ト, the value is much higher and it's easier to tell when it was made. However, in 1871, copper and silver coins were issued, which gives the exact year of mintage.

Chinese cash coins I think are the easiest to identify, especially comparing with Korean mun. There are over a thousand varieties.

Oh, I just meant Japanese coins of the 20th century, where there are only 3 emperors/eras to learn.

You're not considering Meiji, right?

Chinese coins in the Taishou and Shouwa era are almost as easy. Cast cash coins, like the one just identified, are like the old cash from Japan.

Oh, you're right.  I don't really collect recent-generation coins, so I was actually only considering the Showa, Taisho, and Meiji Emperors, but not Akihito.
