It would depend on the type. There was a rifle, carbine, and engineer's model. If it was in good shape, I would say that the rifles would go for $150 to $200, the carbines for $160 to $210, and the engineers (which are fairly rare) for $250 to $300. Many of these rifles were sporterized and that would lower their value somewhat.

If you're referring to the Argentine Modelo 1909, it uses the 7.65x53 cartridge... a rather uncommon round, but surplus ammo can be found for them. On the side of the receiver, it should say something like "MAUSER MODELO ARGENTINO 1909", while the bolt guide behind the chamber should have the manufacturer's markings.. on mine, it says "DEUTSCHE WAFFEN-UND MUNITIONSFABRIKEN, BERLIN", although there were a couple other locations where these were manufactured. Also, on the top of the chamber, there should be an engraved crest.
