The U-suffixed is added to the numbering on the back of the card to identify it as part of the 1991 Fleer Update set, and not the 1991 base set. Identical in design to the base set the Update set features players who switched teams during the season, as well as those who made their debuts.

If you mean what brand, than look on the back of the card, everywhere. You should find something that says Topps, or Upper Deck, or Fleer, or Goudey, or something like that. If you mean the name, it's on the front and back, and if you mean what date that look on the back of the card, look at the bottom, and then if you can see in really small letters it will say for example Topps 2004.
The "U" that precedes the number stands for Update on cards from the Fleer Update set. For example U25 would be the 25th card of the Update set. Traded or Update Sets are a set of cards, usually factory packaged, that features players who switched teams during the season, as well as those who made their debuts. Topps, who started this trend in 1981, is most well known for traded sets. Other companies also produce traded sets, although they refer to them by different names such as "Update" (Fleer) and "Rookie/Traded" (Score) sets.

On any sports card RC will mean rookie card. You also have XRC which are extended rookie cards. XRC were from extension sets that were released in the later half of the previous year, i.e. Topps Traded, Fleer update, etc. There was a time when XRC were worth less than the regular RC. Now with time older sets like the 80's the XRC's can be worth as much or even more than the "true" rookie cards. Of course, value is based on the player, condition of the card and if it's been professionally graded.
If you mean the card than it is the 1909-11 T206 Honus Wagner card # 499
what do you mean 'wonder cards'?
Not really there are way more Yu-Gi-Oh cards out there than baseball cards + they're easy to counterfeit so people will still make them in the future, lowering their value.
