I have an almost complete set of German Empire half mark coins, most in XF or better, some PCGS MS66. The exception is the 1908F which has CV of $2000 in F. Except for the overdates. I regularly monitor EBay for these overdates but rarely see them. There are 14 of them and I have only ever found one. If you have any you are willing to part with please contact me as I am interested in buying. Alternatively, if you are aware of another site which may offer a better chance than EBay please let me know.
