The Bavaria coat of arms issue that was perforated came out in 1870. http://www.stamp-collecting-world.com/bavarianstamps_arms.html
From the scan I cannot see what the colour of your stamp might be.I presume it´s brown. If so,the stamp should be Michel no.60 from 1890. The stamp was printed in great numbers,more than one billion.Printed over a periode of about 20 years different papers were used and many different shades exist.In perfect condition it is valued € -.50. This design was used in Bavaria from 1874 till 1911. From 1867 till 1875 a similar design was used. These were in Kreuzer currency.On January 1st, the Mark was introduced in all Germany.One Mark was equivalent to 35 Kreuzer. I do not collect "modern" Bavaria,but only the stamps of the Kreuzer-periode (1849 - 1875) Bavaria was the only german state,what issued own stamps till 1920. Württemberg also had own stamps,but ceased to have regular stamps in 1902.Service stamps were issued there till 1920.
