Found at colonial house . Sword pommel , top of cane ? Something else

[Gregg3131]

I found this at late 1700s property. Extremely heavy !! Possibly silver Any thoughts on what this can be ?

Possibly silverplated pewter -- which I've never heard of being used to make sword pommel-cap. More likely to be a walking-cane's top.

I would guess a handle from a mirror
