Help with antique golf clubs?

I have a set of Spalding tour edition LTD cold forging golf irons.SW PW 9 8 7 6 5 4 3 in excellent condition with a bright chrome finish used one season and put away.They look near bran new.I found a site called house of forged who no longer deals in antique golf clubs that told me used they were worth 500.00 and yes in deed they were a collector club this has been many years ago I may be interested in selling them any one with info on this club or where I might find more info Thank for reading
