BGS graded cards question

[abt3509]

I was wondering if anyone has done research to know how much (in %) a card increases (in sale value) based on a BGS grade. For example, how much of an increase would a Jason Heyward Bowman Chrome Auto that grades BGS 9 or BGS 9.5 get over a raw card?
Then taking it a step further, what would be the % increase (or multiplier) of refractor auto cards compared to the base chrome auto and so forth with the rainbow? And would the same % increase or multiplier remain the same for refractor BGS 9 or 9.5 cards?
I hope these questions make sense. It is hard to put this in writing.

I guess I am wanting to know if there is a way to make an accurate guess at how much a BGS 9 or 9.5 graded refractor auto would get when I only have sales information for the raw chrome auto.

Any help with this or guess that you may have would be appreciated.

Thanks!

I generally sell BGS 9 graded cards about 10-25% over raw - depending on the player, and BGS 9.5's from 50-100% over raw.

It's going to vary greatly depending on a few factors: player, how difficult the card is to grade, how many have been graded, etc. There is no set multiplier for grades but since it seems like you're asking about Bowman Chrome cards, generally, it's around 1.5-1.75x for a gem but there are plenty of exceptions.

Yes, I am mainly speaking to the Bowman Chrome cards.

The best way to go about it is to research recently completed sales on ebay. Most chrome card 9.5's settle in around 1.5-1.75x their raw counterpart price. There will be a premium for low population cards (usually the first bunch graded) and for ones that are notoriously hard to grade (2002 Bowman Chrome Joe Mauer, 2003 Bowman Chrome Hanley Ramirez).

For the most part, bowman chromes are very easy to grade.
I realize that that is where "the money"is, but base bowman
Cards are more difficult to gem, especially the older releases
