I've never searched whole boxes of coins. Only customer wrapped rolls. Particularly with halves, would it be worth a try to start searching boxes of halves?
Yep, you should do some boxes if you can. But it has been my experience that CWRs produce better than boxes on average. My last two boxes produced two 40% coins. My last 340 in CWR produced five 40% coins and one 90% coin. Trouble is I just can't get $2k worth of CWR per week.
