I believe that 1883 in listing should be 1883A based on a coin I received today and on eBay listings which all seem to picture 1883 with an A mintmark.

Sample eBay listing: http://www.ebay.com/itm/Greece-50-Lepta-1883-Condition-UNC-MS61-Hellas-Coins-148-MD1-/222349049887 (zoom crown side (reverse))
Krause lists without mintmark but I think that is error.
