There are a lot of non-sports sets still not listed here yet. I add them as I come across them, but I don't have a whole lot of knowledge of tobacco era cards and almost every new set I add to my collection pre-1970s is news of it's existence to me. The field of non-sports has been active since 1879 and we have very little added from the 1800s. Of course, information on them is hard to find anywhere.
Racing is almost totally accurate...I spent a great deal of time and effort making sure everything was listed and accurate. There may be a few that slipped through the cracks, and then there are the promo issues that pop up from time to time that have been missed, usually from the early 1990s. I do know of a couple sets not yet listed that there is no other known compendium of knowledge about on the internet- but even with my collection, which is the largest one known*, I don't have everything and can't properly fill in the missing numbers yet. In due time, I hope.
*- my 1/64 NASCAR diecast collection is over 5000 unique cars. Before health reasons forced me to quit collecting in 2013 I had all but an estimated 100 Racing Champions issues and all but about 500 total issues ever, from between 1980 and 2013. Many of the cars issued until 2005 came with trading cards. The listings here on the Database are the only place on the internet to find accurate information about the card sets issued with the cars.
I'm not as knoweldeable about open wheels and drag racing, although I do enjoy them the knowledge isn't there, and there may be listings for those missing.
I also don't want to make it sound like I am the only one working on this. Tom and Adam, better known as Lea DeFoote and Spazmatastic, have also put a great deal of effort into making sure the checklists are correct, and other people have as well too, I believe.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
