*Message was: In determining the value of a carpet, I have always computed the piece's value points and then multiplied them by the cofactor for the country or region of weaving. The values have always come out pretty close to the actual retail sale price. The cofactors were used to determine the value of a particular piece against the yardstick price. The cofactors I use have become outdated in the past year. Can anyone direct me to a new list?
