I'm no expert but the 1896. 10 Corona is one of the rarer coins in the series (mintage: 210,734), is not a restrike but a circulating coin and has a fairly high catalogue value not to mention the melt value alone is $124.93 so the seller is selling it below melt value which makes me question it's authenticity.
If you can find any proof it's a original then by all means go for it, 100 euro is a great price, however because of the reasons I stated before I think it's fake...
