That's pretty cool. I've always wondered why the "California" is left off BGS shields in that state. I've always assumed for visual clutter reasons, but "Interstate" doesn't get left off Interstate shields, so…
Anyway, here are two recent additions I made. The first is this MN-32 marker:

Interesting thing about this one, is that it's made with extra-thick aluminum, making this shield exceptionally heavy. I don't have a calipers handy, but visually I'd estimate the stock is probably between 1.25x and 1.5x thicker than standard. It's probably also one of the last shields to have the MnDOT logo printed in darker blue at the bottom center, as I believe they stopped doing that around 2000 or so. (Date code at the bottom left, "999," means the manufacture was in September 1999.) They've also since stopped printing manufacture dates on the front, too.

I liked having the logos and dates printed on the front—it gives them character and also tells me when signs were made/used, since the stickers applied to the back often get removed when signs are scrapped—but if I'm not mistaken the FHWA told DOTs to knock that off.

The other is this unique 18x18 Pennington CR-65A shield:

As you can see, it originally had the number 63 on it before being brutishly removed and reapplied with 65A. Note that the A is not a standard letter, but rather a hack job made out of three strips of black vinyl. The seller had a bunch of other Pennington County shields in better condition that normally I would've gone with, but I chose this one for its character.
