Spaghetti Santa Planter

I have a few Spaghetti Santa Planters of which I posted them on eBay but upon further investigation, I see that some of them are selling for a couple hundred dollars. I was wondering if I could find out more information and get an appraisal on them to see if I am selling them for too little or just the right amount. I am not familiar with any of these. I just know they are probably from the 1950s. I do not see any markings of them. I also put a poodle image as well. Many people seem to be interested in this particular one and am curious if there is something special about her. I have a matching one where the poodle is standing instead of bowing. I appreciate all your feedback.
