Valuation help on some coins - Swiss, Spanish, German, English [решено]

Hello All,
I have been given some coins to value (and return).
Please could someone find the catalogue price for a 1906 Swiss 1 Franc; a countermarked One Shilling 1836 William IIII; a 50 pfenning Deutsches Reich 1877 A (mint mark); and Un Centimo Un Gramo 1870.
I appreciate this will take some time but I would like all grades mentioned if that is ok. This is not for me...but for another person; so the valuation is for their own purposes and the coins aren't for sale. I guess that the countermarking de-values the piece? Anyway many thanks in advance.
