Prices have surged for sure. Take a look at a '54 Johnston's Cookies Aaron. It's not a Topps rookie, but it is still a rookie. And it's far scarcer than Topps as well. A very undervalued card IMHO. Unfortunately if you want a Babe you might need to pony up. I don't see those going down anytime soon. And with Mick, a good choice would be a PSA/SGC 4-5 '54 Red Heart. Another nice looking card that can be found with nice eye appeal in lower grades and not break the bank. Good luck with your hunt!
