Opinion on various Sandy Koufax autographs
 

Before wasting money and time getting them authenticated, I was hoping folks with Koufax experience could weigh in on some of the Koufax autos that I've managed to pick up over the past 15 or so years. Some I am confident in, others not so much (2 of them I'm almost certain are common forgeries). I added numbers to the photos to make them easier to reference. Thanks in advance!

alot do not look good. #15 and #8 are probably good. There are a few others that might be. Lots of nicer ones for sale on ebay like https://www.ebay.com/itm/SIGNED-SAND...AAAOSwqjJenKvM.
Don't know seller but nice vintage price ok

Thanks.

#13, #14, & #15 were all TTM.

#9 and #10 are vintage sigs. The #9 is a postcard postmarked in the 1960s.

I don't think #5 and #16 are genuine... they were purchase on eBay many years ago when I was more naive.

I know vintage Koufax and 9 and 10 look off. The n in #10 and the slant. The K in 9 looks off tho he did have similar ones and the x too and the S. I own over 100 Koufax from rookie 1955 vintage to fairly current. I could go either way on 13 and 14. No on 6, 8 and 11 could be good.
No to 1,2,3,4,7,10,12, 16
Not sure on rest

I appreciate the input. Here are the results so far from opinions gathered here, on SCN, and Facebook. Admittedly, only 6 people rendered their opinions, so take it for what it's worth.

It seems to be the consensus that 1, 2, 3, 4, 5, 7, and 16 are fakes. All were eBay purchases, so that's entirely plausible.

Numbers 6, 8, 11, 14, and 15 were (almost) unanimously regarded as real.

There were mixed opinions on 9, 10, 12, and 13.
- #9 is a vintage postcard with a postmark date of 1967. I think it's real.
- #10 is supposedly an early signature, and was purchased from someone that I trusted based on their other offerings... all period pieces that looked 100% good.
- #12 was purchased from the same collector as #11, and I believe it is good partly by association with #11, who everyone believed was authentic.
- #13 was obtained TTM within the past 10 years, as were 14 and 15. I'm quite sure it's authentic.

#'s (3,4,5,7,16) are bad. The rest are good.

Thank you. I actually like #1 and #2 as well, but no one else seems to. #2 has actually failed PSA once, but to me seems like the messy signature he was giving out at ST a few years ago. I feel like anyone forging Koufax would have tried to make it look more conventional. And #1 looks good to me.

you forgot NO on #5:D, The easiest one

No to 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 (agree with assessments above for 9,10,11,13,14)

you only like 1 & 2 because they are yours Corey:D, they are almost as bad as 5 & 16:), but not quite. You got yourself quite a mess ter piece there and got beat like a red headed stepchild by e-bay

I usually stick to buying only vintage Koufax signatures because it is slightly easier to determine if they are legit, but even then it is difficult to know if it is secretarial because his signature changed over the years he was playing. Plus I think his vintage signature is better looking.
But I believe 8, 9 and 13 are fine, and maybe 11, 14 and 15 as well. Don't like the rest.

So you're on board with 9,10,11,13,14 being real, and all others fake?

I don't have much money invested in them. The ones that I did buy on eBay were only ~$20 ea, so I figured there wasn't much to lose. If I ended up going 50/50, I still considered myself ahead of the game.

yes, "possibly".:D on the lower end, as in "WOULD NOT BUY LIST"and don't forget the $25.00 in authentication rejections :D that we know of.:D Take care and enjoy!
