[UPDATE] Following the publication of this story, the eBay pages mentioned in this story have vanished from the auction site. We've reached out to an eBay representative for comment.

The original story is below.

Two separate eBay auctions for iPhones with Flappy Bird installed have attracted dozens of bids, both of which have top bids so far of over $90,000. Creator Dong Nguyen pulled the game from app stores yesterday, meaning the mobile hit is now an instant collector's item.

Flappy Bird isn't exactly "rare," however, as it's been downloaded more than 50 million times. The brutally difficult but simply designed mobile game is still playable on your device if you've already downloaded it.

With six days to go, seller "pindrus" has received 74 bids for an iPhone 5S with a copy of the game. The top bid on that auction is $99,900. Separately, eBay seller "Kristenater91" has received 65 bids--with a top bid of $90,200--for an auction ending this evening.

It's possible that bids are being run up by trolls, as was the case with super rare NES game Nintendo World Championship late last month. We won't know for sure until the auctions end.

Nguyen removed Flappy Bird from iTunes and Google Play yesterday, saying its removal was not related to legal issues (it bears resemblances to the Super Mario franchise), but rather because "I cannot take this anymore," he said, referring to all the attention coming his way.

Nguyen is forgoing a major payday by pulling Flappy Birds, as he revealed last week that the game was pulling in an average of $50,000 per day in advertising revenue.
