Hi Keith,
These are a common hinge for any Salice distributor, and you could go out to dinner at a nice restaurant with what you will save. I have attached a link to Salice distributors in the U.S.
Our distributors stock the nickel finish rather than black.... but it's the same hinge.
There are also numerous on-line retail sources. All of which will have these hinges (Nickel plated) at a price well under $5.00 each + the mounting plate if you need it.
Here are a few to check-out:
