artifactual value

n. the usefulness or significance of an object based on its physical or aesthetic characteristics, rather than its intellectual content

Notes

An item may have artifactual value because it is a particularly good example of the class to which it belongs. For example, an albumen cabinet card photograph may be collected because it possesses many key characteristics of that form and is in excellent physical condition, although the subject of the photograph may be unknown. Artifactual value is a key component of intrinsic value.
