Machine Or Customer Wrapped Rolls, Which One You Search More?

As previously stated, I have NEVER found any silver, proofs or NIFC in any of the rolls marked with 4 dots (In 5 years of searching this area). I have better things to do with my time than move $3000.00 worth of halves from one bank to another with zero chance of financial gain. But hey, if you're not working 55-60 hours a week & feel like searching around here I'll even hook you up with the bank whose vault teller searches all half dollar rolls BEFORE they leave the vault (and draws a little flower on the wrappers).

I think it's a hit-and-miss on anything, but I prefer cwr when looking for older coins as many were people unloading their change jar. When looking for newer dates, i.e. parks quarters, I like bank wrapped as I usually find mostly newer dates in them.
