It's a pretty funny experience building up doubles of cards from a 100-year-old set, but that's exactly what I've done.
First, two new cards for my 1910 Murad T51s: Mount Union College and Worcester Polytechnic Institute.
Then I hit a double in back to back lot purchases with these Armour skiers.
Another lot I bought contained a State University of North Dakota footballer, which means I now have two of them.
I'd be more than happy to trade away my duplicates, but I really prefer to get tobacco cards in return, preferably for a Murad College Series card or two that I don't yet own,.
Also, I now own 27 unique cards of this 150 card set, which puts me at 18% complete. If I can add 5% each month, I'll definitely meet my goal of 50% completion by year's end.
