I just ran across this knife and would like to find out what I can regarding it's collecability/worth. It has Imperial USA/Prov. R.I. on the blade as well as Ingersoll Rand/Professional Tools. It's has a 16553 as what I believe to be a model number as well as raised lettering for A.J. Foyt Jr. 1972 Daytona 500 Winner etc. on one side. The other side has A.J's face and car with Daytona in the background. What do you think? Thanks, Tim
