Buck knife model 521a7

[remshotman]

I am looking for information about a Buck knife model 521a7. It is a 3- 7/8" lockback with brushed stainless handles and four turkeys etched in color on the handle. I know it was made in 1991 because of the + on the blade. I would like to know if it is rare and about what it is worth. It is new and in a box.
