You could be looking at anywhere from $300 to over $1000, dependent on the markings, overall condition, which factory it was manufactured in... however, the ones worth over $1000 are going to be very few and far between, and $300 - $700 is a bit more realistic.
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.
Markings on the rifle will indicate exactly when and where it was made. So- what markings are on yours?
Mauser 98 from WW I.
Depends on the country of origin.

Usually the sn and caliber
Send me photos of the rifle and of the markings, and I should be able to narrow it down for you. The email address is in my bio page.
Could be worth up to $500 for an immaculate, all matching rifle. It replace the Mauser Model 1871, used a 7.65x53 round nosed cartridge, variants of the rifle were also adopted by Turkey and throughout most of South America.
There is no such thing as a Mauser 1819. Model numbers then were based on the year they were introduced, and the first bolt action rifle wasn't introduced until 1824. Additionally, Paul Mauser - who founded the company - wasn't even born until 1838.
The Mauser es340b was a single shot .22 long rifle. It was made too look and feel like a Mauser 98K. It is not a sniper rifle. It is a target rifle.
Impossible to answer without a detailed description of all markings.
What is it (rifle, shotgun, handgun) and who made it? What are the markings/words on it?
