I have about 25 brass doors from a old mail box that was used in my trailer park. are they worth anything as is. or are they just scrap
The prices of old brass range from $2-$5 depending on their conditions and size. You can talk to an antique dealer around your locality to help you quote the price. He may check the conditions of the metal before giving you a certain price.
There are many collectors of brass mailbox doors, especially if they are old doors with raised numbers or letters on them. Check them out on eBay or at a local antique dealer.
