Antique Gold coin set- Do you make money from them?

Tweet

I am holding one Gold and Silver set of 4 coins of 'Baby Jesus and and the 3 Angels", since the last 3 years. This is a limited edition set brought out by a Company, Gold Quest Intl. minted at a well known mint in Europe. I purchased this set at a price and I am now trying to sell it. Astonishingly, I am told that it can only fetch the bullion price and not for its antique value. I feel cheated. Is anyone of you holding any such product or have made money selling it on Ebay? I need all your feedback.
