27.9~mm; 11.0gm Looks to have some silver content; is that 'B' a mint-mark? Wilhelm 5th? Properly German or Prussian? Thanks...
What you have is a 2 mark coin of Wilhelm I, King of Prussia from 1861 to 1888, Emperor of the newfounded 2. German Empire from 1871 - 88. The alloy consiste of 90 % silver and 10 % copper. B is the the mintmark of the Hanover - mint, wich was closed down in 1878. Your speciemen is quite worn, as those early Emire - coins usualt are, butnever the less very collectable.
