There's old flips and then there's older flips
I believe there are 3 generations of SGC flips. The 1st generation is the one that may be problematic on crossover, but the 2nd and 3rd generations are the same in my estimation. The 2nd generation has the gold bar on the back. The 1st generation has a very different looking front of the flip than the 2nd and 3rd generations.
