This is getting ridiculous!

Same story. Comparing duplicates, just checking for quality upgrades.

The major difference is that the center graphic of AU JUP 2s3 has been enlarged, and the circle of text moved out close the rim to accomodate the enlargement.

There are also several minor differences:
AU JUP 2s2 - darker pink rim, brighter whites, flat finish.
AU JUP 2s3 - lighter pink rim, subdued whites, shiny finish.

Previos versions are AU JUP 2s (white rim), and AU JUP 2s1 (pink rim and RHC mold).
