I am glad that I could help you find the monetary value of your collection. As to the actual value, well, that I could never say. I figure my collection is worth in the area of $8000-9000. However, my most valuable item is a beat up, hopelessly used copy of
T1 Village of Hommlet that might fetch 50 cents at auction. This is because it is the only item I have left from my days of playing starting in the late 70's (I gave the rest away to fellow soldiers when I was discharged from the Army in 1992).
