How many points do Pokemon Cards need for screw down holders? And if I got a screw down, would I be able to put the card in a penny sleeve, and then into the screw down?
It’s the amount that the place you put the card is recessed (I think).
@frostyfluxy - A “point” can be translated as a unit of thickness for trading cards. It is used in defining the thickness of card stock. It is commonly abbreviated as pt.
@tolan - I occasionally use [Ultra Pro 35 pt. Gold Magnet] recessed card holders. In my experience, I cannot use a penny sleeve; the length and width of the penny sleeve exceeds the recessed area dimensions.
@frostyfluxy - I apologize; I provided incorrect information. I thought it pertained to font sizes, too. I edited my reply accordingly.
Point (Typography) ≠ Point (Thickness)
@frostyfluxy - You’re welcome 
UPCCC previously had a similar concept – the karma system. It has been removed. I cannot remember if there was a discussion about a potential gratitude button (i.e. thanking a member for a specific post) or another equivalent concept.
