Sometimes CWR are great, other times they're awful...
A couple of weeks ago I got 1,000 CWR from one of my banks... the two bundles of 500 coins had distinctly different wrapping. One bundle had 18 wheaties, including an AU 1955-S... the other one had only one wheatie...
The key is perseverance... the more you search, the more likely you're going to run into a collection dump or "better" coins. And the same holds true of MWR - found an XF-45 1909 VDB amongst a group of MWR I bought that same day!
CRH Nickeloholic. 1,600,000 nickels searched in eight years! Have found FOUR complete Jefferson sets!
