I think the size and mass are on the 2x2 already shown, 22.9mm and 0.7 grams.
The coin shown is representing as being from Emperor SHIH TSUNG
AD 1723-1735 reign title: YUNG-CHENG, AD 1723-1735
Examples I have found are around the 4.0 gram mark and sized from 25 to 28mm diameter. So this one looks light on in both indicators. It should also be brass IMO.
The reverse is S-1453, "BOO CIOWAN" (Board of Revenue mint).
On the obverse, the period title is made up of the top and bottom characters. The bottom character seems a bit odd.
I'm far from knowledgeable in this field, but it seems suspect to me.
It should look like this.

Someone else will know for sure.
