Your top coin is indeed a wide 0.
The wide 0 variety is a "money coin".
There were at least 5 different wide 0 reverse dies used, for a mintage of 400,000 that represents a significant portion of the total number of dies used thus they aren't as rare as current pricing would indicate.
Look for the price of the wide 0 variety to drop greatly over the long term as supply exceeds demand.
"Dipping" is not considered cleaning...
