Welcome to the NGC chat board.    The rough surfaces and ill-defined details clearly identify these pieces as replicas of the sort sold by the thousands at venues such as souvenir shops over the decades. The rare genuine Continental "Dollars" look like the one shown here: 1776 PEWTER 'CURENCY' CONTINEN | Coin Explorer | NGC (ngccoin.com).    If you believe that a coin has collector value, you should not touch it with your bare hands except by its edge if you must.
