MLB Authentication Coding

[dangerzone79]

Hey guys. Since MLB has changed their authentication website, they no longer have the dropdown menu to choose from all the letter codes. HZ, EK etc. Can we compile all the codes we remember? I wanna write em down. Helpful to have when you have a holo with a letter rubbed off. Please add whichever ones you know. Thanks!

HZ
EK
JB
JC
BB
LH

AR, AT, BB, BC, WBC BB, CR, DR, DT, EK, FJ

This short list came up when googling mlb hologram

MT is on some older stuff

The old system still works on a desktop.

The new system lost information for items with multiple entries. This is a huge issue for my collection.

If the code has partially rubbed off, you can actually mail the ball back to MLB to have the sticker replaced. I've done so successfully.

I've heard a few stories of information lost. Has anyone contacted MLB about this? I don't have any that I've found in my collection that are missing a description. Surely the data isn't lost, right?

I really don't want to screen capture every description for every ball in my collection.

The only reason I can access is because I had the window open from last week. If i open a new window and go to it, then it goes to the new system

I saw the new system yesterday. I'm not impressed.

does anyone still have access to the old site as I have three items that have no letters, all numbers.

What to those two letter codes mean? Is there anything to them, or are they just random?

[TBM]

Some of the codes have meaning:

WBC is the World Baseball Classic

As for the others, I have no idea. However I know the Royals have commonly used HZ, JB, JC and EK in recent years. I have some older Royals stuff with MR.

I think it has more to do with the region than anything and that they just get whatever rolls of stickers from that supply.
