Well to me it is worthless, when i find them i keep them so that some unsrupulous types don't get hold of them & try to flog them of as genuine,there is another sort that do get bought as genuine on occasions,a lathe is the tool involved in this type,hone one coin out,machine another down to the right size then fix it into the honed out shell,all types are fairly easy to pic if you know what your looking at,but some grubs do get away with it.
Originally they were magician's coins,double heads or double tails so thats where the scammers got the idea from.
Having said that this one sounds like it could be easily identified & there are some legitimate collectors of this type of thing so as long as you disclose everything in your listing i can't see any problem with selling it .
