Wooden Beveled-Glass Mirror; How Old Is It?

This is one of Mom's leftovers. an' there's another of similar make, but it's an oval with a longer handle (no pics). Both of them share a loose glass that rattles in the frame, but won't come out. I've seen a few of these with a cord stuffed into the edge-gap as a means to secure the glass. I wouldn't be surprised to learn she (or her mother or sister) brought them both from Holland when the family immigrated in 1924.
~5" diameter, ~8" long, ~3.8" thick...no cracks, chips or splits in the wood; the mercury mirroring shows peripheral deterioration an' the glass surface is moderately scratched. Is it 19th C, or newer? Thanks for lookin'!

 

I do think 19th century. Possibly as early as the 1860s but produced for decades.
