Is the Delaware 1994 quarter misprinted in gold worth anything?

It wasn't "misprinted". It is an ordinary quarter that was gold plated by a promoter and sold as being something special. Someone probably spent it after they tried to sell it to a coin dealer and was told it was a damaged coin worth only a quarter. In addition it couldn't be dated 1994. All 1994 quarters have the old eagle design on the back. Delaware quarters were struck in 1999.
