PQ or Grade?
For your registry sets do you go for PQ for a grade, or the highest grade you can afford? I have a MS66RB Lincoln Cent in my type set that I absolutely love. It has a beautiful deep ruby red toning to it. However, I keep my eye out for an MS66+RD to "upgrade" it, but rarely see them come up for sale. Well one popped up on eBay today, but it doesn't wow me. It's not much money, but I'm wondering if I should get it, or keep the 66 and be happy with that. I don't want to get caught up in the competition aspect of registry sets. How do you handle such a conundrum?
