Well, it looks like the mark of Sigmund Bierfreund (ca. 1619/20-1702; Master 1654). But it goes without saying that 17th century Nuremburg beakers are exceedingly rare. We all know from this forum that 19th century Hanau makers were skilled at the art of reproduction, and the new definitive reference Nürnberger Goldschmiedekunst makes it clear just how widely Nuremburg pieces & marks were copied.
A photo of the beaker might help, but even so, you'd probably want eventually to take it to an expert for examination.
Good Luck!
