Incorrect attribution of coins of Schleswig and Holstein [решено]

Coins N#310524 and N#310525 are described as copper Sechslings, and the reverse lettering is transcribed as 1 SECHSLING, but the photos show the reverse lettering 1 SCHILLING and appear to be silver.

Are these patterns  of the 1851 silver schilling of Schleswig-Holstein listed as KM-25?

The titles and face values have been changed to 1 schilling.

You can submit a change request to make the composition silver. 

Thanks
