I am curious about whether this is a McCoy or not. The USA letters are indented and the other letters are raised but not prominent to the eye. The pottery is not perfect it has unevenness in the glaze and on the top lip?

Answer:

Your lovely vase is McCoy. Sometimes the glaze was thicker than other times and filled in the area of the logos. Your vase was made in the 1940's and came in pastel colors.
