1970s? Reuge Music Box w/Shadow Box Lid

I am trying to identify a Reuge Ste. Croix Music Box with a shadow box lid containing dried seeds and grains. It is wood with dove-tail corners (5.5 x 5.5 x 2.5") in very good to excellent condition. It plays "I'd Like to Teach the World to Sing" after cleaning and using WD40. There is no other number on the box, however the number on the barrel of the mechanism appears to be 5533. I would like to know about what year this was made and the estimated market value.

Good
