looks like a typo to me, which means its value is about a year's worth of typo revenue. if you really are getting $5-$10 on only 30 impressions per month, then it's worth high $xx. but having the typo being an extra key at the end, it could also be sold as StructuredD, but that doesn't seem to flow or look all that well. nonetheless, you it could bump it up a couple of $xx.
