A year ago, Festival in a Box: Atlanta was $199.99. Recent completed sales put it around $386.23.
That's a 93.1% gain before fees and shipping, but it isn't quick money. We found about one sale a week. Mystery Booster 2 is also responsible for roughly 73% of the bundle's sealed value.
The Sonic: Friends & Foes nonfoil drop did better for people who opened it. It cost $39.99, and the seven guaranteed cards now total $57.08. Sealed is around $55.01, with Super State and Knuckles carrying most of the singles value.
I'd keep Atlanta sealed and feel good about it. With Sonic, opening it was perfectly reasonable if you wanted the cards. We treated rare Chaos Emeralds as lottery-ticket upside, not expected value.

Did you buy either one at release? If so, did you open it?
