If I were selling them, and could find someone to buy them at $25, I would consider that a very good price.
If I were buying them, I'd be looking for them from $5 to $10 apiece. There are enough of them out there, including copies, unfortunately, and I put them in the same class, price-wise, as Imrie-Risleys, Staddens and Rose figures. I'm a buyer, in that case, and I look for them from $5 to $10, generally. There will be variation, of course, that will impact the final price.
Hope that helps, and hope I'm not meddling!
Prost!
