Not Stardust. Stardust description, per Pete's LOM Spreadsheet is "Crystal base with red, yellow, green or blue single-color frit embedded in the surface. Rough texture. Iridescent finish."
Here is a picture of an older Stardust bag from the late 1990's and picture of newer one from 2018 or so..
The $227.50 bag of 100 does seem high. Maybe someone thought (knows) that they saw a valuable P&R in there - like a Watermelon? - but I don't see anything that would pump it up that high. However, the bag of 100, which is not rare but is not easy to find. I sold one, as part of a group, in the $50 - $75 range.
