I can't say I've ever tried, but it's unlikely to be the monarch that's the problem. I'd put my money on either the condition of the coin or the price you are asking.
He's the one that let the Nazis invade Norway through Sweden. The coin is XF silver and selling at $5.00.
Book price in XF is $3.00 by my reference. I tend to have a hard time selling Swedish coins in general. I think there are just more on the market than there are collectors to buy them.
