Haven't had much time to peruse eBay lately. Heck, I did not even realize Topps Heritage Minor League cards had hit the shelves yet. I happened to see a true auction for a Bryce Harper Topps Heritage minor league auto card and at the time of this writing, it's up to $455. Not too bad. Only about three hours left, will be interesting to see what it ends at.
