Help Identifying Old Chinese Coins Please

@ara, yes all the ones with "dots" in the field are definitely modern replicas. I believe this is done to simulate the roughness and porosity of the surface of cast cash.

For that bottom one in the first pic, pls post pics of just that one along with the diameter and weight. Thx.

I'll have to agree with above comments, tin addition, the color of these coins are off - far too 'brassy' looking. they should be a bit darker.

I agree with Sap, these are both Chinese cash of Emperor Qianlong (aka Kao Tsung and Ch'ien Lung) 1736-1795, Boo Ciowan (Board of Revenue) mint in Beijing

These are very common coins, though still interesting and good additions to any collection. They look authentic to me (I agree the other ones, in the group of nine shown above, with bumpy surfaces, are modern replicas).

Upper photo should be rotated 90 degrees clockwise, lower photo should be rotated 90 degrees counterclockwise.
