Is there a gold 1941 us nickel with no d marking?
No. All US nickels minted in 1941 contained 75% copper and 25% nickel. If you have one that appears to be made of gold it is probably gold plated or colored with some other substance to give it a gold appearance. Sometimes with nickels that have not been circulated [used in everyday business] tarnish can develop and at times this can give them a golden like appearance depending on the environment they have been in. Also there are chemicals that can be used to create a tarnished look on the uncirculated coin.
