I don't think the price of the blue balloon should go down as the seller didn't know about prices, and unknowingly sold it for 250TBT. The person just asked what collectible of mine would be 250TBT, and sold her balloon because she believed that it was worth that much. Since that was just one person, I don't think the price for it to drop that low.
I agree with sap that was a drastic dump in price due to a sale
