Scott - I'm nearing completion on the T3's and have completed the T9boxers. To me they are one set of 126 cards since the boxers are from #51to #76, as opposed to a set of 100 baseball subjects & 26 boxers.I always picked up the affordable ones that crossed my path and Inever cared too much about the backs. There are 5 different backsand w/o too much trouble I have a variety of them all.The ad backs are only issued in the high # series #77-126 and as arule they are pretty easy to obtain and roughly half of the high #'sI have are indeed ad backs, so ndon't pay a premium for them.PSA & SGC grade any card w/ a pin/nail/tack hole as a PSA-1/SGC-10and in my opinion rightfully so, since the card has been mutilated.With that said you can get some great looking low graded cards thatpresent well for minimal amounts.There always seems to be some graded & ungraded cards on eBay so youshould have plenty to choose from and you'll probably run out of $$$before your run out of cards to choose.Have fun, and within time you're set will grow by leaps & bounds.The Fred Clarke still awaits ....jayHere's some that are sitting on my desk. I take a few out now & thento enjoy them.
