Trying to figure this one out. Does not look like any year or trace of year (on Obverse at 6 o'Clock) Does not look cast. From what I can determine its the W2/R1 variant. The 'J' Hamburg mint was only struck in 1949, so it would have to be that year???? Any other suggestions would be appreciated.
It's definitely a 1949. I am not exactly sure but, I believe it was a clogged die. According to Krause, some of KM#104 are known to have no date or half dates. Worth anymore than usual? I don't know...
