It looks like a subfossil or very faded honey cowry, Cypraea helvola. Shells often change colours as they slowly become fosilised even though they look perfect, a similar colour change can be made artificially by baking the shell in the oven. Some unscrupulous dealers have done this in the past and tried to sell them as 'new species' or 'colour forms'.
