It would be helpful if you provided the measurements of the bracelet (length and width), and examined it closely including the clasp for any hallmarks/gold stamps.
Once you know the measurements and the metal karatage, you should be able to search online for some comparable bracelets to give you a rough value.
If you post that info here, likely some PSers will try to assist you in finding similar bracelets.
Do you want to find a similar bracelet or sell your own?
You can contact a jeweler and ask them about the approximate price of the bracelet. But it is better to contact a familiar jeweler, so that he will tell you how everything really is
