Yes it seems that way however if you watched my video i found an older wheat penny in the BWR but got more volume from the CWR. thanks
For me it depends on the coin. For pennies BWR are better because with CWR people are looking at the coins and if they see a wheat penny they flip out thinking they hit the jackpot and horad all of them. However will all other coins (As long as your looking for the current design) CWR are better because it doesn't get mixed up with new coins like it does in BWR.
