What condition is it in. That determines the value.
Depending on condition, between $100 and $200.
No published sn data.I can say that the Mossberg model 151 semi-auto .22cal rifle was made from 1950-1951 if it is the model 151K.The model 151M was made from 1946-1947.The model 151M(a),151m(b),and 151(c) were made from 1947-1958 and were close to the model 151M with minor changes in the buttplate,and sights.
50-150 depending on condtion.
The Mossberg Model 151-K was made for two years only: 1950 and 1951.
IF the rifle has all sights, etc, has not had stock modified, there IS a modest collector's interest in the older Mossberg 22s. $200-$250 is an average price. They shoot VERY well.
Value is driven by make, model, condition and originality. With the 151 M, often the rear peep sight or sling swivels may be missing. If complete, values may run from $100 to $200 for an excellent specimen. There IS some small collector interest in older Mossberg 22s.
