Pappy is iconic and has been for 10 years.
All these crazy new ploys to charge more .... ARE (technically) working, but not to the same multiple like PVW (10x on p23.... 300.00 to 2.8K)
"Where am I getting my numbers"
DEVR is 2500 MSRP and sells for 7-11k depending on batch.
Recent OFC are 2500 and sell for 3300-4000.
"Final Reserve" (45 years old) has MSRP of 4400 and sells for like 5-6k tops. Oops. actually at retail... https://dewinespot.co/products/james-thompson-brother-final-reserve-45-year-old-kentucky-straight-bourbon-whiskey
Bourbon that commands 10-30K per bottle is typically stuff that came out prior to 2015 and is scarce now that many got consumed and only very few unopened bottles remain (to this point, they got consumed because htey were cheap bottles back then, many folks are likely kicking themselves when they drank a 100.00 bottle of Willett that now sells for 10k, 20k, even 25K in a heartbeat once listed).
To your point, YES this is limited to 240 bottles. But, if you want one all you have to do is offer 2-3x retail and someone will come off of one because it will be a recent release.
Added notes - double eagle very rare is 20 year old whiskey, and limited to 299 (i think) bottles. The average price for that batch (batch 1) is like 9-11k depending on the day. I think the first one sold for 15-17K.
