Is it using cardstock or on a regular coupon paper? I might lean toward it not being in the database, the only difference with others (like the 2016 Topps coupons) is there is a lot of Topps advertising on the cardstock, where this is more just a picture showing what the coupon is for, if that makes sense. I think some people keep these in their collection though, so I'm sure its of interest to some people, but again, maybe not worth adding to the database.
