Contemporary counterfeit
Barber dimes exist, but aren't terribly common. Your coin is outside
mint tolerances, but that could be the result of being buried in the ground, exposure to acid, harsh cleaning, or other factors.
The cast
Barber dime counterfeits are usually lead-based,
very crude, are pitted and lumpy, and easily scratched.
The transfer die struck
Barber dime counterfeits are very weak on the design details and are typically silver-washed (jewelry plated) brass. They usually used costume jewelry based brass alloys. The silver wash wore off quickly and the brass is usually visible on those.
The photos are a bit out of focus, but your coin looks like it has plenty of design detail. A specific gravity test would give the answer. US coin silver should have a specific gravity of about 10.31.
