“Gold chains have been found in coal.”
Several artifacts, including gold objects, have been documented as having been
found within coal, but in each case the coal is no longer associated with the
artifact. The evidence is therefore strictly anecdotal (e.g., “This object was
left behind in the fireplace after a lump of coal was burned”). This does not
have the same evidential value as having a specimen with the coal and the
artifact still associated.
