About your bicentennial coins... I live in the USA and there are a lot of companys that do odd things with coins. They will gold plate coins or they will do painting on the coins like the state quarter and sell them as collectibles.
On E-bay I saw a set similar to yours that was gold plated and a gold plated dollar coin that didn't sell for $15.
