You are just kidding about cracking out the #2 slab right? Silver has in my opinion some of the finest affordable registry sets in the system, and probably some of the most interesting to read , I have learned more from reading Silver's Superboy registry set gallery than any other I have encountered. it is so informative that it has almost driven me to collect Superboy's.
His Sugar and Spike registry set is amazing and inspires envy, and HAS driven me to start collecting them, although I fear I will never find the first two issues, if I do acquire those fist two issues ( regardless of grade if the are blue label/complete) I may get the first 20 issues CGC graded and start a registry myself although it would pale to Silvers collection.
