What is the age and value of a JC Higgins Model 66 Automatic?
your shotgun was made by high standard just prior to 1980. value
will depend on condition mostly. i can estimate that one in good
condition will cost around $200.00 to 300.00.
High Stadnard stopped making the model 66 for sears when the Ted
Williams 30 made by Winchester was introduced inteh early 1960's
High Standard was completely out of the shotgun busines by early
1977.
THis link is to a chart that shows the dates when these shotguns
were cataloged by Sears.
