A little FYI: 

Pawnshops, or pawnbrokers, are stores that you can get a form of loan by 'pawning' your valuable belongings as a collateral. If the loan wasn't paid back (with interest) by the scheduled time period, the collateral item would be taken by the pawnbroker and they would probably sell off the item to cover the loan you owed.
