Yahoo's quotes are posted by a third party data supplier. So, the key question is where does Yahoo get its data. As they note:
"Historical chart data and daily updates provided by Commodity Systems, Inc. (CSI)." Therefore, as far as data quality goes how good is CSI? If they are no good, then Yahoo is no good. If they are good, then Yahoo is good. There is a chart on CSI's website from a 1999 Futures article that shows CSI had the lowest error rate. Is there more recent data that indicates otherwise?
