It won't have one since Stevens didn't serialize their inexpensive shotguns until the GCA of 1968 required it and the 5100 was made c. 1931-1941.
My experience for similar guns (like Stevens 311, Stevens 5100, etc) is that your gun is likely worth 250-300 in good condition with little room for movement either way given bad (but working) condition or excellent condition.
The value of ANY firearm is based on the exact make, model and condition, You did not give us enough information (serial number provides none of the 3 items we need). Eastern Arms was a brand name used by Savage for guns sold mainly by Sears. Value in good condition is likely around $100.
My grandfather recently gave me a Stevens 5100 double barrel 12 gauge and I did a little digging and found that Stevens produced the 5100 from 1931-1941. Value, I'm not sure about. I havn't had mine appraised yet. Shoots nice though :)
Is that the serial # or model #? I have one marker 19HF on all separate parts. My thought was that is the model. But my other id # is 5000, so what are the odds we have the sane gun model 1oo units apart?... Value is $150-$250 depending on condition. Less if it is broken or rusted and a little more if like-new. The 5000 and 5100 are not serial numbers. I'll bet my JC Higgins 16 gauge looks just like your guns and it is also numbered 5100. Stevens introduced the Model 5000 (in 1923 or 26, depending on which reference you believe), changed the model number to 5100 in 1931, and then to 311 in 1941. This gun was manufactured until 1989. The Springfield name was discontinued in 1948.
$150-$350 depending on condition. email@example.com
It was made from 1931 to 1941. Value for a 12 or 16 gauge would be $150-$250 in useable condition. A .410 or 20 gauge could bring twice as much.
That's an older gun, should have the chamber length checked. In good usable condition, about $200-$225. www.countrygunsmith.net
5100 is the Stevens model number, not a serial. These were made c. 1931-1941. The plastic was called "tenite" and often broke.
Stevens 5100 was manufactured from 1931 until 1941
I have just purchased one myself, however it was a 16 GAUGE. I have checked into the value and have been qouted anywhere from $225.00 to $375.00 depending on condition. Andrew Kimmen
Around $250, depending on condition
This is a Stevens gun, probably a Model 5100 or 311. Value in like-new condition could be as much as $200. If rusted or busted, then about $20.
I'm pretty sure if you lay it side by side with a Stevens 5000, 5100, and 311 you'll find it is identical to one of them. Useable Stevens doubles sell for $150 to $200 and some people will pay as much as twice that for the 410s.
If this is the Colt 1878 Frontier model serial # 5100 , then it was produced around 1881.
The model 5100 Stevens shotgun has a plastic stock
A SxS in useable but not like-new condition will bring between $100 and $250. A 20 gauge or .410 will be in the mid to upper part of that range and a 12 or 16 gauge in the lower to middle part.
$80 to $5100 depending upon the condition of the coin.
Assuming 12ga, $150-$250. firstname.lastname@example.org
I'd bet that is 311A instead of 3114. Savage/Stevens re-named the Model 5100 as the 311 series about 1942 and discontinued the Springfield name in 1948. Depending on condition, it should be worth between $150 and $250.
It was manufactured by J Stevens between 1920 and 1948. There should also be a model number on the right side - probably 5000, 5100, or 311. Value will be $150 to $250, depending on condition.
