Value of Goebel Musical Dolls?

I have 2 Goebel musical dolls and would like to know the year and price of them please.
The first is a Goebel Michafel #408 of 500, a Betty Jane Carter doll, designed by Bette Ball. He is wearing a white tuxedo, has blond hair, and plays "This guy is in love with you". It is a limited edition, still in original box, in mint condition.

The next one is a Goebel Elizabeth # 746 of 1500. It is also a Betty Jane Carter doll designed by Bette Ball. She is a musical the plays "I could dance all night". She has blond hair and is wearing a white and pink ball gown with pearls. A limited edition, still in the original box and in mint condition.
