See above for a description of Fiestaware and why it's here under uranium. Radioactive Fiestaware is quite popular, and plates like this routinely go for $20 or more on eBay. Naturally I'm not willing to pay the going rate for this kind of thing, so I lowballed them for a few months until this one somehow escaped other's notice and went for $6.86.
