The Madison Gracie is genuine. Those were never really faked, as far as I remember. That caviar-type pebbled leather was more than most counterfeiters wanted to deal with.
Hopefully someone will have some cleaing suggestions. One thing you don't want to do is use straight saddle soap or any thick opaque cleaner, because anything that has any kind of color or leaves a visible residue will get into all those "valleys" in the leather and is almost impossible to clean out. Try just a thick fabric with a lot of texture like an old terrycloth towel and just dampen it and gently go over the bag one area at at time. Then gently wipe another old towel over it to dry the bag. Again, that's just a guess but it's the first thing I'd try.
The color may be Beechnut, and the Price when new was $242 in my Holiday 1995 catalog, maybe 5 or 10 dollars less in 1994 when that one was made. The F4E- prefix means it was made in June of 1994 (bags made in 2004 would use "04" instead) and it was made at Coach's plant in Italy (the "E" is the plant code).
