Unkown mark on a chinese silver coin dish

[bgp2000]

Gurus,
Please help to identify this silver mark from china or hongkong as the photo.
The hallmark can be read as "AN800", it may be a 800 silver dish with a 1911's hongkong 1 dollor coin.
I can not find similiar mark on internet.
Thanks in advance for your any comments.

Are you sure the first 2 letters are "A" & "N"?

Maybe A & H

ummmmm... Probably made by some post-1950 Hong Kong company. I saw a few disks or ashtray were made by modern Hong Kong silversmiths or companies embedded old silver coins.
