How much are these art noveau Mauser pieces worth?

[genesisvh]

I have two pieces of Art Noveau vases with intricate details. The larger of the pair has the marking of Mauser, I believe. Images are below. I would like to know their worth. Thank you in advance.

Size of the marked piece ?? What does the other one have on bottom ?? Do they match ??

The larger one is 22" height and 9" wide and has the marking with the unicorn and fine sterling label. It is located on a plate at the bottom of the vase.
The smaller one is 17" height and 7" wide and has no plate on the bottom but it is stamped with 2 lines of numbers. on the first line it has 5328 and on the second line it has the number 1. They are both identical except their size.
