i typically dont send or read in-game msgs-i usually have to delete them right away, sometimes without reading them (i feel really bad about doing this :(), bc the msg menu makes my game glitch, freeze, and crash (i think i have too many friends). i was able to see ur msg though, and ill answer your question-the retired beta items are the ones that were pulled from the shop and suddenly became very rare (supposedly) and high in demand. such items include: the pink slipper chair, the red teepee, the cyan ariel treasure bench, and a few others. however, despite them also being pulled from the shop, the matterhorn bobsleds pin (not the host prize) and the enchanted tiki room 3/9 pin have been very low in demand and not as valuable-idk why lol :D
