historical end of day response values don't match that of Yahoo.com and Investing.com (data from both sites match each other, polygon data does not)

I believe polygon data you're referring to does actually match that of yahoo. Note that polygon output is OCHL whereas yahoo is OHLC. Also, some of this polygon figures seem to show higher resolution whereas yahoo always rounds to the 2nd digit.
