Obverse doesn't match any known Shilling diagnostics/attributions in my books. Breen reports that Shillings of this type should be around 4.66 grams. Probable counterfeit.
This probable fake coin is still for sale on eBay! http://www.benl.ebay.be/itm/190799938418?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648 Seller uses some tricks here: [h=1]UNKNOWN ANTIQUE? ANCIENT COIN? SAYS "1625" NOT SURE/ MAYBE TOKEN?[/h]The pictures too, upside down etc... Best regards, Marc DC Marcantica
