Erin Morris is auctioning off an Illinois-shaped Lay's Classic potato chip in an effort to raise money for treatment her pet ferret's adrenal disease, the Chicago Daily Southtown reported Thursday.

She reportedly noticed her unusual chip Tuesday while eating a sandwich and reading about Melissa and Emily McIntire, who auctioned their Illinois-shaped cornflake.

"I noticed one of the chips in my hand looked familiar," Morris said. "I flipped, flipped, flipped (through the newspaper pages). I thought, 'Hey, my chip looks like Illinois, too!' "

The chip's highest bid is $6.50 on eBay and the auction will end March 29.
