Do Coin Companies Sell TPG Rejects?

I can't see any reason why a coin company would not sell TPG rejects, if they can see a profit in it.

I do not collect slabbed coins for a number of different reasons.
As a potential customer of a coin company,
if I can see a numismatic cherry pick at the right price, I may well consider adding a TPG reject to my collection, if the price is right,
although as a general rule, I do not collect NCLT anyway slabbed or not slabbed.

Other collectors, that are a little different to myself, are very happy to add un slabbed NCLT to their collections. For example, silver round stashers (bullion), or World silver crown collectors (numismatic).

Yes it's just bullion. I don't mind mild imperfections, damage, but if I can see it easily with my eye, no magnifier, it's going back for exchange.

There is a market for slabbing modern bullion. I think low mintage and mint errors are good reasons to slab modern bullion. A friend of mine mainly buys TPG ASE. I don't care much for them, but I have a few. For me slabbing/grading is best for older collectable coins. To each their own.

Of course they sell them. What else are they going to do with them, melt them down? Throw them in the trash? Even if the grade on the slab is higher than it should be they will ship them out. Most of them will stick simply because of what it says on the label.
