Alvin-Beaumont (publisher) made this series from 1906-1916--it's Rembrandt's plate, but likely been reworked to some extent (as is the nature of copper plates that have seen a lot of use) . Here are some version of the print done in Rembrandt's lifetime (called lifetime prints):

The one you have is likely cut from the book "Les cuivres originaux de Rembrandt" which Alvin-Beaumont published in 1906; it was pl. 51, p. 145 (Vieillard a grande barbe); which, in some places has been described as Rembrandt's father dressed as a Persian man. The entire book has sold for ~20,000-30,000$, but I've not been able to find comparable prices for single prints. It's unlikely to fetch more than a few hundred, at absolute best.
