Lizzie knows scottie collectibles. she would probably know best on this one as far as price. she should be around today at some point.
Because some folks might be prohibited by the shipping (which you can't help. And Linda i forgot sometimes UPS can be cheaper), I wouldn't do the "start at $9.99 thing" and hope for a bid war among 7 people, though of course it only takes two to tango. I would start them at a price with a BIN or such that you would be comfortable with if they went for it. These are way unique compared to cast iron that i have sold so it might not matter as much. But still, i would wait for Lizzie.
I would, since dog collectors can be quite serious folks, give them a few days to pay (and state you will) in case someone snipes through aucitonsniper or other such surface. these aren't the typical cast iron scotties people are used to seeing, or at least come to mind for me.
