St George box-Greek

Appears to be a silver plate of St. George(the front) and was made into a box,

welded to another box to make it the way it looks now. A handle is on each side. One person

suggested it may have been a tea box.  My husbands father who was greek, always told him there was a piece of Christs cross in the box. however, the box was opened to find two byzantine coins.

What a surprise. Any help on this would be appreciated.
