50-500 depending on specifics.
Karabiner 98 (wartime production), Yugoslav M48A, Argentine Modelo 1909, Swedish M/96, and Brazilian Mod. 1908.
Depending on EXACTLY what you have, 100-1000 USD Have a pristine 1909 German made with all the markings but it has been sporterized. It is in 7.65 cal. Looking for a possible value.
If it's in .30-06, you'll see a reduction in value, as the Modelo 1909 was chambered in 7.65x54, not .30-06. Probably $100-$200.
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.
Never made a model 1909, that's a patent date on at least a model 12 pump, but value is greatly dependent (on model) and condition, condition, and condition.

Not knowing how many variations of the Chilean Mauser were made, or which variation you're referring to, the assumption will be made that you refer to the Mod. 1908, which was a variation of the German Gewehr 98 Mauser. This stock, and stocks of other variants (such as the Argentine Modelo 1909) should have some degree of interchangeability with the Mod 1908, although it is possible that some sanding or other minor alteration will be necessary.

The exact value of a 1909 Ithaca double barrel shotgun stagecoach model would actually be dependent upon a number of factors. The most important factor that would be considered is the condition of the shotgun.
Impossible to answer without a detailed description of all features and markings.
