1600s Chinese coin question

I have one of these, but I'm having trouble matching it on the NGC website.

https://en.numista.com/catalogue/pieces61445.html

Is it this one?

Not same one

https://en.numista.com/catalogue/pieces61445.html, This one is Shunzhi (Shun-chih)

NGC: http://www.ngccoin.com/price-guide/world/china-empire-cash-km-297-1644-61-cuid-112121-duid-289283

Figures! Thanks for your help.

So....how do you know?

Numista says:   1667-1670
NGC says: 1644-61

The catalog numbers don't match. Does the writing described by NGC match the characters on the coin? If that's the only way to match it, I have some learning to do :-)

bbybugs is right, Krause does a very poor job documenting Chinese coins, the dates on Numista are correct.
