I just inherited a Clown Doll Collection---HELP!?

I have inherited a large collection (4 HUGE boxes plus single-individual dolls in each of 7 smaller boxes)of Clown Dolls that run from the ridiculous to some that appear VERY nice and expensive.

Is there a definitive website that has info on various clown doll-makers where I can research these pretties and see what I should sell them for pricewise?

I'm sure that some of the makers' names on these clowns are top of the line but others I'm equeslly as sure are clowns that were added because they were cute or funny and not of any real value--except to add to the number of dolls in the collection.

Some of the names are:
Betty June Carter
Seymour Mann
Geppeddo
Emmitt Kelly Jr (2 figurines)
Lizzie High

Probably the ones I find the least appealling (ugly)will be the ones worth most!--seems to happen often.

Any advice from a "clownite" would be greatly appreciated.
Thanks
