I have attached a scanned image of a coin my mother has had for over 40 years now. She received it as a gift from my Grandfather and she has now passed it to me.
I have searched the net and all sites I came across indicate the mintage of this coin in 1886 was limited to a few thousand. Most sites also state that in 1886, that Philadelphia was the only location to strike these coins in 1886 and that the marking under the eagle would be blank. However, the coin I have has a "S" under the eagle. A couple of sites state that in 1886 San Francisco didn't make an 1886 Double Eagle, but I do see them making them in 1885 and 1887.
Can anyone clarify the mintage of the 1886 Double Eagle Gold coin. Were they produced in San Francisco in addition to Philadelphia and other sites?
Does anyone know the value of this coin?
