Stirring up a hornets nest

California has the Year Of Manufacture (YOM) which requires both plates, manufacture year registration sticker and plates not in the system

Re-pop registration stickers can be found on ebay. My plates came with the correct sticker.

And of course a small DMV fee and small $10 annual fee. I believe the new black plates are vanity plates with higher annual cost

Some extra info:
The new legacy plates are
$50 to order either sequential or custom
$40 for renewal
$15 to transfer the plates to another vehicle
$35 for substitute plates
