Here in Germany it actually is quite common that auctioneers use grades such as vz./stgl. (xf/unc) describing averse and reverse of a coin. Numeric grading only is applied when coins are being sold slabbed and that is not the case very often. But grading here differs from numeric grading anyway so I guess we get along quite well :)
Always looking for coins from Brandenburg/Prussia!
