HalleygatorThanks a bunch for enlightening me!
Now I can hopefully use the terms at the PROPER times and not seem so stupid.
Or, I can just call everything a "baseball card" like I have always done and "pretend" to act like I know what I am doing! 
The good news is that I just bought 35 back issues of Vintage Baseball Card magazine on EBay ... so sooner or later I should know what the heck is going on.
Until then ...
NOBODY should bid on the 1873 Boston card because it is NOT a cabinet and is therefore worthless!!
