Wally World (Wal-Mart) has a Topps 2009 Baseball factory set w/ Mickey Mantle card on the window on the box for $49.99. Don't see this in Beckett Guide and worth risking getting it?<br />
<br />
Also I'm new on here, but been collecting since 1977. What are Serial Numbered when you talking about cards and what does the red and green bar means by each card?

It's worth getting it if you like it and want it. Sometimes there's a strong secondary market for retail-only chain-specific bonus cards, sometimes there isn't. That one likely hasn't seen a lot of movement so far enough to price it, but I can't tell you for sure.<br />
<br />
Serial-numbering on cards means there are numbers on the cards indicating how many were made and what specific number that card is out of that amount. For example, 2009 copies of each 2009 Topps Gold card were made, all sequentially numbered from 0001/2,009 to 2,009/2,009.<br />
