I'm not a super expert, but I can help!
Either you have a remake RT, or a vintage European one.

The vintage American flat hands, as first edition dolls, go for a little more than their curved hand counterparts but not by much. (Have no clue on the international variants, but I heard they are more valuable). Here's a rundown of the vintage American doll versions:
Flat hands - first edition
Curved hands - no pet - second edition
Curved hands w/ pet - third edition
Some consider the dolls with pets as "second edition" but technically they are third edition. They made the baby dolls with pets since the very beginning, so it's sometimes difficult to tell the difference if you don't have them w/ their original boxes.
SSC has recently gone down a bit in value so that helps buyers but not sellers. The Berrykin dolls, regardless of country, imho, are the ones who continue to hold their value
Let me know if you need any other help w/ SSC!
