your list is great, especially using the ACC# (American Card Catalog Numbers) for many of the post 1950s cards too. some of those Ive never seen numbers for.
there are others differences that I didnt mention on my list I made earlier, some are minor things like narrowing down the year more accurately.
you have 1887 Buckner Gold coin as having rounded corners or square corners, Im sure the cards that are rounded are from wear.
There are some N284 cards that were hand cut from an ad poster and these will have a portion of a large letter or 2 from the black ink overprint that was printed on the poster.
the black ink can be partially erased (see image below)
the 1904 WG2 and WG3.... are now known to be from 1906
Ullman NY Giants "Art Frame Series" Postcards are more commonly known from 1906, yours is listed under 1907
1910s Parker Brothers game cards, are known to be from 1913 and there is only 1 player Napoleon Lajoie, but there are 2 different color cards, red or blue
the set you have listed as 1910s Brush Postcards, you have "Ty Cobb" in the notes section, there are est 10 different players in this set, so its not just Cobb, unless you want the most expensive one
the cards show the player with the Brush automobile, rare cards
here is whats thought to be a complete set...

1910s T214, is more well known to be from 1915

1910 T3 should be from 1911
just saw that you have a set called 1910s WUnc. ornate border (2 listings), those are the same cards as the 1912 "J=K" sets I mentioned in last list, so you may want to remove the ornate border listings so they arent listed twice. .... the "ornate border" name was the old name before the complete box was discovered with the name of the manufacturer and product on the box. in reality the smaller cards are on 1 side of the candy box while the larger ones are on the other side and the diecut part is part of the endflap
you can see both types on my page here

1910 WG4 is from 1914
1916 E135 (and the related sets) is now known to be from 1917 you have the 1917 D328 Weil set correctly listed, there are 5 total related sets (backs)
some are newly discovered such as the Merchants back... here is a list

Im thinking the 2 sets you have listed as 1920s WUNC Playing Cards are these 2 sets here (both are very rare cards)

the 1926 Holland Ice Cream cards are now known to be from 1925 (they won the series in 1924). the 1926 date was changed a few years back...
1930 Uncle Jacks are from 1933
under 1947 W571, you have perforated listed 2 times, there is only 1 type (square), they have baseball/boxing players on one side, with actors or cowboys on the other side, they were made by Hess Shoes. here is a link (below) to info including the Exhibit size cards too. and the square corner 1947 D305 should say 1950's, they were thought to have been released a few years after the round corner bread cards (also many of them are fake too (reprints)

when I get a chance Im going to have to edit my pages as well, to add some of your ACC #s
