UMC 10 gauge brass shotshell

I would like to know when this case has been made.
It is empty and had been probably reloaded but it is still in good conditions.
It is 76,34 mm long

without checking my notes i would say after 1886

Thanks,
any idea of its value?The seller asked me 5 euros,but I got it for 3 euros because it is fired and reloaded

10 gauge, all brass, pre WWII (at least), US ctge in Europe : even 5 Euros would be a good price (it is the price of a cigarette box!)
