In going through my great-grandfathers coin box, mostly collected from East Africa during WWII, I found these two Chinese coins. Looking through the Numista catalogue makes me think the first one is a
1 Cash - Qianlong Boo-chiowan (thought it's wider than the diameter listed there), but the second one is different enough that I can't seem to find a match. Which is now making me think that one or both are fakes! I've seen other posts where replicas have raised dots in the background, but that doesn't seem as apparent in mine. Any help would be greatly appreciated!
Coin 1
26mm Diameter
Around 6g (my scales don't go into decimals sorry!)

Coin 2
23.5mm diameter
Around 4g
