I believe this https://en.numista.com/565330 was meant to add the $1 coin in the picture. That coin is already in the catalog. N#20185
If the intent was to add a set then the set is also already in the catalog. https://en.numista.com/catalogue/set.php?id=2876
Delete the coin page but it's probably worth moving the pictures to replace the ones in the set.
