He claimed that generally he considers a cleaned coin to be worth about a grade lower than the same amount of wear would be uncleaned --- so an AU would be worth an XF and a
F about a VG.
Would you all agree?
No. As a rule of thumb with many exceptions for less common coins and the method of cleaning, a cleaned coin will lower the value 75% to 90% or more (down to melt value) over an uncleaned coin. Only ANACS among the top 4 TPGs will slab a cleaned coin and give it a net grade (which won't be near the uncleaned grade) thus giving it a little more value over the same cleaned raw coin.
