Do you have a default price for lost volumes of bound periodicals?  Do you loan them out?

We loan ours via ILL and when they don't come back,  we need to supply a price to our billing staff. But these things are usually old, irreplaceable, and lack comparables to base a price on.

I'm thinking either set a standard price per volume or no more lending. I'd like to know what others do. I'd also like to know what your default price is,  if you have one, as we need to bill for a couple that went lost.
