30-06 is a common, popular caliber, over 100 years old and still in production. Lots of different models of rifle have been chambered for 30-06 so without knowing the make, model, age and condition of your rifle there's no way to answer your question. Google your rifle by make and model and you should start to get a rough estimate.
Mauser Waffenfabrik never manufactured a .30-06 rifle. You MIGHT have an M1917 rifle, which can be worth over $1200 in good condition and all matching serial numbers.
I believe you meant "30-06" which is generally pronounced "thirty-ought-six." If someone says, "this is a 30-06 rifle," they probably mean the rifle is chambered in the very popular hunting round 30-06. They might also be referring to an M1903 or M1 Garand rifle. Both of these rifles were used by Americans in WWII.
25-06: The 25 means that it is a 25 caliber. The 06 means that it is a longer bullet than a regular 25 caliber bullet

The rifle is probably a BAR
