WSP does an inventory finding an AR15 missing. This would suggest that WSP has the serial number for the rifle. Maybe this is too simple, but it would make more sense for WSP to share the serial number of their missing rifle with the gun shop owners asking them to check their inventory for the rifle.

Kennedy half dollars after 1964 do contain silver and are worth more than 50 cents...from 1965 to 1970 these half dollars contain 40% silver and at today's spot silver price are worth about $1.40 each.
