The Model 188 was made between 1979-89. In excellent condition it is worth $45
In circulated condition it has no added value.
Made in 1979. In excellent condition it would be worth around $35
Depends on overall condition, mileage, options, etc...
The receiver was made in 1979 but may NOT have been assembled as a shotgun during that time frame. It could have been assembled in 1980. Value, as always, would depend on the current condition of the shotgun. Best bet would be to take it to a local gunshow (in an appropriate case) and see what the folks who rent tables will offer you for it. Most likely you could add $50.00 to $75.00 from what's offered.

A 1979 Susan B. Anthony coin is worth 1 dollar (face value) still to this day unless in a condition that is UNC.
In 90%+ condition about $700 for a 20 gauge and about $550-$600 for a 12 gauge.
If it is in good condition, probably around a thousand dollars.
