Roycroft Christmas Carol- Value

Backstory:

Every year, for the past eight or nine years, I gave my girlfriend a
copy of the "Christmas Carol" I have always tried to give an unusual and
relatively rare copy. It commerates our first Christmas when prior to
going to a local production of "A Christmas Carol" I gave her an
undistinguished copy of the Book.

One year, I happened upon a Roycroft "Christmas Carol" together with
another "Christmas Book"

The Question: As I remember, the Roycroft suede was red (ABE gives the
color as green) and immaculate the other "Christmas Book" was green and
again immaculate.(Both Suede)

Assumimg they are in still the same condition, can anyone give me a
guess on a price. The best ABE can come up with is four hundred dollars
for a relatively tatty copy.

I am as sentimental as the next person (more so probably) but if she
could realise substantial returns or a trade for a more stable volume, I
would like to advise her to do so.

Thank you, Ted
