Sandy Koufax' recent signed balls
 

I know there have been some posts on here lately about Koufax's signature looking sloppier as the years go by, but this is really bad:

How can JSA authenticate these?

Do you have a copy of the JSA COA?

No...but the eBay seller said he has a full letter (although it wasn't posted):

Here are two other examples of his recent autographs:
The 1st is a sit down autograph that he did for me at a private signing in April- May of 2015 on full, unsed tickets to his 1st and 2nd no-hitters.

The second autograph was applied to a ball at Spring Training and was provided by a poster on net54 within the last year or so.

One is pretty easy to authenticate, but the other is a real challenge.
I don't realistically know how you could authenticate the OP's ball or this one in this thread IMHO. :rolleyes:

That is my ball from Spring Training. You have to remember that an in person signature at a venue like Spring Training is going to be rushed because there are people everywhere and time is ticking.

He shows JSA proof on some of this other items but not this one.

Packs,
I completely understand the difference between a sit down sig and a rushed one at Spring Training & I meant no ill feeling towards you or your ball.
Please accept my apology if you took it that way.
What I meant was that unless I had seen him sign this myself, I would have a hard time believing that this was Sandy's autograph...

No I totally get that and I wasn't thinking that you were doubting me at all. Just wanted to reiterate for people who don't normally do the Spring Training or game day signature hunting that the atmosphere there is tense and for someone like Koufax, he's hitting and running a lot of the time.
