I'm picturing a $30,000 Reverb listing with a Make an Offer button, and a line at the end of the listing body stating, "No: The mere act of seeing my listing does not signify that the Parker-branded something-or-another you won in an eBay auction last week has suddenly jumped in value. Nor is my asking price in any way indicative of appreciation, perceived market value, or whatever the final sale value will end up being. Serious offers only."
...I'd find it funny, anyway. Best of luck with the windfall for new gear, Nef. I know you'd also prefer that Toxic go to a good home.

We just had a Trans Butterscotch Nylon Fly (312039BSS) sell for $7,750 twelve minutes after being listed on Reverb. Recently sold Nylons include 260049 for $7,388.81, and P0802188 for $5,499. We don't know how much 243059 was sold for in its private transaction between FlyClone members.
Other previous serials and prices for Nylons include 067020 for $4,140.27+shipping, 031050 for $2,054.95, P0809128 for $5,099.99, 020050 for $2,300, and this unknown serial modded with Graph Tech saddles and 13 pin-out for $3,550.
The thread also has anecdotal data of VJ buying one for either $2,600 or $2,800 pre-pandemic bubble, as well as his brother buying one for approximately $3,300 at the beginning of the pandemic bubble.
My takeaway is that the Nylon/Spanish Fly remains enough of a unicorn for Fly enthusiasts identifying as classical players that they're willing to pounce on listings when they see them - Cost be damned.
