Quick Question

Sorry if this has been answered already. Is there a good resource to look up all the error cards, and UER and what specifically, is the error

NGS428

Best database I have see is the trading card DB. Example here is 1991 Donruss. They actually tell you what the error or variation is if you click on the card.
