Manufacturing date of a H&R model999 22 long rifle handgun serial number AU 0 69 6 7 8
I hope you are still around to get an answer. This site says the AU prefix in the serial number indicates 1980 manufacture date.
Value depends on condition, so if you can, post some clear pictures. Could be anywhere from $150 up to a probable maximum of $350-400 for like new. If you have the original box and paperwork, that adds value. I see some listed on a gun auction site for up to $700 new in the box, but most completed auctions are selling for around $450.
