I'm looking for a non-working coin door. . . . I don't really have any expectations for it, other than it needs to be square

. I figure I'll find an old, beat up one, and repaint it.
I've bid on a few on ebay, but I really don't wanna pay 45$ for something that I am only using for "looks".
If anyone has something sittng around that they would like to sell, please let me know!
