1936 is a very common date:
here are the mintages of the year before and after compared to 1936...(ROUNDED TO THE NEAREST MILLION)
1935p- 58,000,000 1935d- 12,000,000 1935s- 10,000,000
1936p- 119,000,000 1936d- 25,000,000 1936s- 15,000,000
1937p- 79,000,000 1937d- 18,000,000 1937s- 6,000,000
This is source from my 2010 redbook
Also- to add! 1936p is the only year in buffalo nickels(of all mint marks) to exceed 100 million minted making it the most common dated buffalo nickel.
The top 3 most minted buffalo nickels by year and mint are:
1936-p (118,997,000)
1937-p (79,480,000)
1916-p (63,497,466)
Hope this helps!
