I don't have an exact answer to your question because I actually have the same question. I too have a leather jacket by Dinosaure, only mine is brown and that particular model is called Dallas. It says so on pink label on the inside.

I bought this coat from a friend of mine for 70 Euros but he told me that he payed just under 300 for it and I believe he also said that it was on sale at the time. So I'm guessing the store value is just over 300.

I hope that helps.
