Most valuable card in your collection

[Mets/Jets]

Nice stuff guys. I guess my most valuable card can be seen in my sig. I picked it up raw and got it graded last year.

I posted already but just got this in, so it's now this one. It's a purple ref 10/10

I owned this for two weeks in December. Wish I had more money and I could have kept it.

1998 Pinnacle Plus Team Pinnacle Mirror Gold /25

Update:

This is now it.

Based on offers(up to $350), probably will never get that again since Topps released quite a few his autos the last few years. Pulled it in 2006 and was amazed when I first saw the patch. Still tough for me to sell/trade nice patches or autos I pull.

nice bernie

Or THESE because since its a set, i prob put more into it than the card above...

Have to update this now.... (Sorry Cal)

 

[jmagic87]

for me even as a red soxs collecter would have to be this card for sentimental value (found as a bookmark in one of my grandmothers cook books after she passed away

for value one of these

before i traded it this would of been up there also

My 1958 Topps Mickey Mantle is probably the most valuable, or my 1956 Topps Ted Williams.

Whale & most offered
I had 1 chance to buy a copy 6 years ago, and im glad i worked it out.
havnt seen one since. Been offered as much as 7k but i cant move it.
It's my whale. And the best mac card on the planet.

Honorable Mention - This is very valuable
to a diehard Bruce Fan & to a card freak.
This card took many hours and tolls along the GSP
to get signed. I got shutout about 6 times before i
got it signed. To combine music and baseball cards into 1 piece
was a combo i had to have.

Here's another one. It books for $1000 high. Unfortunately, I paid cash for this back in the golden era, so selling it now means I'd likely lose money...which is why it's not for sale:

SEXY!!!

For me, I wish I had better stuff to post, but these would have to be all in the same ballpark:

Mine as well update mine.

These two are probably the most expensive cards I own, based on book value and potential sale value. I have sold several for a lot more... most expensive sale for me was when I pulled a copper version /56 of the infamous 2007 Topps Jeter w/Bush and Mantle shortly after it came out... that netted me about $1250. But these cards here are probably the most valuable one I currently own. I pulled both of them from packs and had them graded. While one isn't a baseball player, it is from a baseball set at least!

that's a ridiculous card, but i never understand the bolded clause above. sounds like the mantra of the archaic LCS owner "I paid X amount back in Y for that card, so I gotta get $X+ now." even though the card now sells for 20% of X.
you've enjoyed the card for a long time, sell it, eat a few $, and put it back in something you'll love more.

New #1 for me (since no blue 9.5 harpers have "sold" in ages).
