Unopened Cocoa Bitters from the 1880s

Would you try it? What would you pay for it?

This is a bottle of Hartwig Kantorowicz Cocoa Bitters from the 1880s that I recently won in auction. Brewed by Hartwig Kantorowicz, who lived from 1806-1871 and in 1823 founded a spirits and liqueurs factory in Poznan, Poland.
