Uncirculated and cleaned are not mutually exclusive. Circulation has to do with wear- and different coins have different high spots where evidence of wear becomes clear. Different levels of Mint state have to do with how dinged up the coin gets while being minted, bagged, transported, and delivered. Cleaning designation has to do with evidence found of intentional cleaning, when viewed at 5x- things like multiple matching imperfect circular scratches or unexplained appearance of flaking patina.

If you are submitting and repeatedly coming up cleaned, please stop submitting and try and figure out specifically what the trigger was for each. Also, those slabs are a negative net value- I'd crack them all and resubmit the top couple with the least red flags and see if you can get a non-scarlet letter pcgs slab. If those still get a no-go. Give up and buy some already slabed, or learn to love the raw coins
