Steve "PSA 1(MK)" indicating that the card would have been in poor condition except that somebody wrote on it, and frankly that's just ridiculous.
With all due respect it is not indicating that the card would have been a 1 it is stating that the card is a 1 and has a mark on it. Buying on the internet has become almost the norm and that qualifier tells prospective buyers that the card has been marked. Some sellers may not be so inclined to mention that fact.
as for the 10 ... a card can't be a 10 and have a qualifier cuz a 10 is supposed to be perfect in every way. gem mint.
this is why they would give a card that otherwise could be a 10 the 9 OC or PD or whatever grade.
To answer the original question as to if the card is worthless. It all depends on the card. A hi dollar vintage card still retains value. A low dollar modern card does not. The answer lies somewhere in between. The mark in this case is on the back, not scribbled across the players face.
As for the qualifiers and the registry, 2 pts are deducted from the grade. In lower grades one is deducted, so in this case your t206 psa 3 mk would grade as a 2 if you were to register it.
The qualifier system has its pro's and con's just like the entire grading industry.
