Well, I doubt it's 2000 years old. The fabric, and radiate-crowned male portrait, are characteristic of Roman double-denarii (often called Antoniniani by modern collectors) from the 260's AD to c. 270 AD. This denomination was originally struck in silver, but the silver content was reduced over time; catastrophically so following the capture of Emperor Valerian by the Persians in 260 AD. My guess would be this is a coin of Emperor Claudius II (r. 268 - 270 AD), but it's possibly a late issue of his predecessor, Emperor Gallienus, c. 260 - 268 AD. Both are among the most common ancient coins of the period, and while they have much historical interest, their value is quite modest.
