Hi Keith,

Thank you for contacting Mearto with your appraisal inquiry.
This is a European backsword; they were popularized in the Renaissance (15-16th Century) and are denoted by the straight single-edged blade and shaped hilt with basket-form knuckle guard (yours is a modified example). These had a heavy-slicing capacity and were favored largely by foot soldiers during wars, gaining widespread usage across the battlefield.

It is, as you note, a fairly primitive example with a wooden handle and the large rosehead studs. In it's current condition, this is worth $300-500.

Based on the photos and information provided, and subject to examination, this is:

An antique Renaissance style backsword
European, possibly as early as 15/16th Century
