Pricing help for older models, various manufacturers

I have some older Ferrari models that are still in boxes, some with the cellophane around them, but all are untouched. I have no clue as to their value or collectibility. Could someone here give me some assistance? If you would contact me by email I won't break any of your site's rules. My email address is: [email protected] and I can send you an Excel list I made with all the info. Thank you,
Frank
