Welcome to the forum @Mormad. Nice packs. I would wash my hands, sit down at a clean surface with good lighting and carefully remove the band and inventory each pack. I would pay particular attention to any and all replacement (star) notes, as they have potentially more value. Some of the $1 Silver Certificate packs had random quantities of replacement notes, and some packs are not always 100 notes. To quote Yogi Berra, “ You don’t know what you have until you know you have.” I took the liberty of editing your photo.
