I suspect some of those names may be a case of sellers not knowing what to call a pattern if they're all talking about ones like yours. Did they have attributions? Coin Dot is usually a cased pattern like this [LINK REMOVED] Fenton Coin Dot.[/url] The only Moondrops/Moon Drops pattern I could find is [LINK REMOVED] New Martinsville's, though that doesn't mean there aren't others. All the patterns I've seen described as Inverted Thumbprint are optic, like your bluerina pitcher. It may be a generic term for the treatment as well as a manufacturers' pattern name. There are a few Polka Dot patterns. I don't know any that match yours, but that doesn't mean much.
I think you'll find that most of the patterns you mention are superficially like yours, but aren't really the same pattern. Your dots are very regular, the circles well-delineated, they're close together, and they're depressions on the outside (right? Hard to tell if convex or concave). It looks like it was mold blown to that shape (except for the crimps), rather than blown in an optic mold to create the dots then blown in another mold, like your bluerina pitcher was. I don't know who made it, but those are some things to watch for, anyway.
