I am looking at 1967 Topps #150 Mantle cards and I notice that on some eBay listings, the card has a red dot above the "S" in YANKEES, while others do not.
All these listings I'm looking at are PSA graded, so I don't think it's dead giveaway for counterfeits either way. But, I just wondered if anybody had any thoughts about it, OR if there are any red flags I SHOULD be looking for specific to this particular card.
The backstory here is that my boss wants to buy one, and wants my help/opinion, so I'm treading a little bit on thin ice and appreciate any input
