As the saying goes - a picture is worth a thousand words - post some decent quality photos showing both sides of the blade and makers names. This will generate some comments as to their general quality/condition - but as has been pointed out, a valuation is not possible.

There are other options available depending on whether you want to keep some of the razors - there are people on the site who can quote for restoration and, maybe you would consider using them in thye future. If, however, you are just after the inheritance - then put them on Ebay and take what they sell for.
