Crossover Results

ArtRossLives

Just got some grades on crossovers -
c55 Dunderdale - was CSA4, now PSA4
c55 MacDonald - was CSA4, now PSA4
c55 Taylor - was Beckett Vintage Grade 3.5, now PSA3 (several fatalities getting the %^$$#$% Beckett holder apart - flying plastic shrapnel....)

About what I was expecting although I had hoped the Taylor would be a 4.

Thanks to the board on threads on submitting crossovers and getting cards out of various style slabs.

Pretty good results, I'd say. Do you remember the subgrades on the BVG card?

ArtRossLives

Yeah, I keep the fragmented holder (what kind of packrat am I turning into?).
Centering 9.5
Edges 6.5
Corners 2.5
Surface 3.5

The card has a faint crease across the lower left corner.

since when does 9.5+6.5+3.5+2.5 divided by 4 equal 3.5?

the beckett graders must be smoking the wacky tobacky

The way beckett grades the overall grade can be no higher than one full point higher than the lowest subgrade. For example you can have subgrades of 10 , 10 ,10 , 3 and the overall grade would be 4

That is assuming each of the values are weighted equally. In my opinion, I would weight the four categories as thus:
Centering (5)
Edges (2)
Corners (3)
Surface (3)

Analytically speaking, that would be a 6.0. But agree that it "can be no higher than one full point higher than the lowest subgrade".

The Beckett grades are weighted differently. I've never seen a card graded higher than one point above the lowest subgrade, but I'm not sure that's an actual rule, or just a result of their algorithm, which they keep secret for some reason. I've tried to crack their algorithm since they started, and a limit would make sense of the problems I've been having. Also, they may not weight the categories, but weight the grades in order, lowest grade getting the highest weight, no matter what it applied to. Assuming a set pattern to the weighting, though, I think they weight centering lowest and corners highest, so the card in question might grade out to:

Centering 9.5 * .1 = .95
Edges 6.5 * .2 = 1.3
Corners 2.5 * .4 = 1
Surface 3.5 * .3 = 1.05
Total = 4.3

This arrangement would give the lowest score, supposing a 1-2-4-3 weighting scheme. Maybe it's something more complex, or less. With a 9.5 centering, the rest of the card would have to be pretty hammered as that subgrade would pull up a card no matter what weight you placed on it.

It is an actual rule - they had it posed on their website. They also have rules about getting a 9.5, I don't think you can have an 8.5 and ever get a 9.5 grade. (e.g 10, 10, 10, 8.5).

I have a BVG 7.5 54 topps williams with 9.5 centering and 7 corners....id like to get it crossed over but wont....how risky is it to get it crossed with those slabs??

loth

Most of the threads on crossovers I read before doing my c55 Taylor suggested taking the card out of the slab. I wouldn't take your William's out unless you're working on a PSA Set Registry with that card. The Beckett slab is a &^%$$ to break and there is a real chance of damaging your card.

If I was PSA I would hate having Beckett slabs sent in. If you decide to break it out I used a sharp strong knife and split pieces of the bottom slab off from the top by pushng the knife in - sending plastic flying across the room. The knife goes all the way through so have it on a surface that you don't care about (I used an old mouse pad).
