How much should I expect an average pawn shop to offer me for these?

I’m just curious about a general percentage of the original price that I can expect to receive from a pawn shop.

Let’s say I paid $900 for a pair of earrings. On average, does anyone have a clue what would be a “fair” offer from a pawn shop?

Thanks for your help. This is the first time I’ve pawned anything and I don’t want to get ripped off too badly.
