PSA pricing percentage differences from one grade to another???
 

Hi Gang:

I am not a graded collector. But I have a question. Are there ''accepted norms" for percentage increases from one grade to another?

Say for example a 1928 Babe Ruth Exhibit card in a PSA 4 if it is valued or sold for $800 what would the same card in a PSA 5 be worth?

Does it go up 10% per grade? 20%, 30%? I assume the higher you go the higher of percentage increase, but for this exercise lets talk PSA 4 to PSA 5.

PLEASE enlighten me!!

Thanks

nothing at all set in stone. always depends on who and how many want it along with rarity

It's different for every card and grade. Any where between 10 and 10,000% from what I've seen.

Henderson rc from 9 to 10 is the example for the high extreme.

Prewar cards often have a big jump from 4 to 5. Not sure about that specific Ruth. I would guess 50-100%.

Scarcity of the grade itself factors in a lot. I there are 50 PSA graded examples of a card, and 6 of those are a 4, but only 1 is a 5, and it's the highest, the premium will be huge. If, on the other hand, there were 50, and 10 were 4's, 10 were 5's, and another 6 were 6/7/8's, the premium would still be there, but far less.

It can sometimes work the other way as well, but more typically with newer cards. What I mean by that is if a 10 is achieveable, and there are 100's of 10's, the 9 is worthless, so the percentage of premium on the 10 is huge compared to the 9.

One other tidbit ... buying the highest graded example is risky. It can pay off if it remains the highest for some time, but if a 5 is the highest when you buy, and a 6 comes along, the 5 will lose value. It is no longer the best known example of that particular card. If it does remain the highest, particularly as the population grows, then it seems to be increasingly impossible to duplicate, driving the price of the 5 upward. SELL!!!
