I'm all for erasing pencil marks on a card, because it improves the eye appeal of the card, which is very important to me. I would not be doing this to deceive a TPG or to anyone I might look to sell/trade the card to, as I would disclose to them what I had done.
I am in the minority (so far) that voted "T card." I voted this way because I assume that the company that mfd. Old Put Cigars used these over-stamped cards somehow in the sale/distribution of their tobacco product. Furthermore, E98s are often termed "ananymous" because their is no indication of the issuer of these cards. To my way of thinking, this situation is similar the M101/4-5 situation; each company that put their ad (whether stamped or printed) on the back of the M101 cards should receive a separate ACC designation, whether it be a "D card", "H card," etc. Some day, after I win the lottery, I will be able to add an Old Put card to my type-card collection!
