GUEST: This was collected by my grandfather. He got it in Mexico back in the '20s. He was a geologist. He came over from Holland with Royal Dutch/Shell. He was doing exploration in the Southwest and Louisiana and Mexico, so he picked this up.

APPRAISER: Well, let me tell you a little bit about the weaving. First of all,the history of the Saltillo. Saltillo is a city in northern Mexico, and it was a weaving center, and the Saltillos were known for the greatest flatware weavings in this hemisphere, or among the greatest. In the Saltillo weaving, there's basically two types. There's the diamond type and then there's the circular type. Now, these are wearing apparel, and they're split here, and then it would be draped over the body. It looked pretty flashy on horseback.

GUEST: I can imagine.

APPRAISER: And they greatly influenced the Navajo weaving.

GUEST: I didn't know that.

APPRAISER: Now, the top was cut, and then down on the bottom, it was cut.

GUEST: Right.

APPRAISER: It's great that it has wear, but this does affect the value. Now, what do people want to see in a Saltillo weaving? They love this deep red color. The dye comes from a beetle and it's called cochineal, and it's this wonderful purpley-red color. So we know this thing is 1850 to 1875 because the diamonds tend to get larger and they come over and they touch the edge. The earlier ones, generally speaking, the circles are smaller, the diamonds are smaller.

GUEST: I was wondering about the age.

APPRAISER: So this is 1850 to 1875. As is, this is a $6,000 to $8,000 weaving.

GUEST: Okay. Now, that's good news.

APPRAISER: If the thing were mint, you'd be talking $10,000 to $15,000.

GUEST: Thank you very much, I appreciate that.
