I bought this big silver coin recently on
ebay, for little under spotprice around $19 dollar (converted from €14). But in the Krause the coin is waaaay cheaper and it starts at: 6.50(F) 8.00(VF) 30.00(XF) 65.00(UNC)
But how is that possible, since there is 22,5 gr. Pure silver in it. The silverprice should be really low, would someone pay $6,50

How can you put a price on coins like this, besides looking at the current price for silver?
Also I was wondering what grade you guys would give this coin, and is it possible that it has a (die) error at the rim below? Or might it be a repunched date, or doubbled die? And are those spots dirt / patina / verdigris / corrosion, and do they affect price in general?
Sorry for all my noob questions...
