Question:

I inherited this green coy fish from my grandmother who lived in lake city, mn.  I know little else besides it has red wing written on the bottom.

Answer:

Besides RED WING USA there should also be a three digit number on the bottom.  If the number is 248, the item is a fish-shaped casserole.  If the number is 247, then it is a marmite (individual casserole) and is considerably smaller than the casserole.  Fish and Chicken shaped casseroles and marmites were made in the mid 1940s and were part of the Gypsy Trail Hostess Ware group.   Assuming excellent condition with no damage or staining, value for the marmite is $40-60 and the casserole $60-80.
