How much are you willing to pay for a Coles mini collectible?

If the answer is $20,000, then you are not alone.

A Gold Coast shopper stuck gold after she put a limited edition Golden Billie Banana on eBay for a starting price of just $10.

With only 100 golden bananas out there, fans are dishing out the big bucks to get their hands on one — and paying crazy prices.

The collectible reportedly attracted a bid of $20,100.

The woman is not the only one to have taken to eBay to sell the rare trinkets, with other sales attracting bids of $3000, $5000 and $12,000.
