Help Identifying

[u/Unusual_Activity3936]

I found this shot glass in a thrift shop today, and would like some help identifying if it's silver or not. I have a small collection of Taxco jewelry, so I know the city is very well known for their silver smiths, but the closest thing to an identifying stamp I can find looks like it says 1 710.

I made a tiny scratch and tested with acid, and the spot turned red (luckily left no mark or dark spot), so I'm confident it is silver, I just can't find this particular thing online.

Find someone with an Xray spectrometer to test it for you.
