1990s vintage Corelle dinner plates mallard ducks, duck decoy pattern, very rare

Set of four vintage Corelle 'mallard duck' pattern plates - this is such a great retro pattern, with the ducks and the deep colors. So 90s! And so hard to find.

These are dinner plates, about 10 1/4" in diameter. All four plates are in very good condition, barely used, nice and glossy without wear to the design.
