I used to play my grandfather's violin...alas many years have past..and by just counting those years my violin is atleast 100 years old..inside it says antonio stradavarious 1734..what have I got? a $100 violin or a $1000 violin..any guesses? where can I get it appraised by a reputable appraiser...denver area??

very good shape..need new strings..hard varnish I think keeps it intact and coolish place..
