I don't do much coin magic, but enough to get me by. I am very adept at many sleights, but decided to start working with coins that you coin experts refer to as "slips". My palming ability has taken a step backward as the ridge is pretty much gone on the coins to classic palm with any degree of consistency. Do I just need to work a bit to add to my skill set or do you guys rough the edges up a bit? If you do, how do you do it? Any help would be appreciated. I'm not afraid to practice, just not sure what direction to go at this time.

Could a coin expert tell me what "slips" are?

Hi, sometimes if my palms are too sweaty I will use slicks or " soft coins" that have the edges remilled.

I made a mistake (I must have been tired, they are called "slicks"; not "slips". The coins are severely worn so that when they slide against each other the noise is minimized. My experience with the coins is that the edges are also "slick" and difficult to palm as there is little to no milled edge left.

The term 'soft coins' is used for worn coins.
Smooth edges are tough!
A lot of pros have the edges re-milled or buy special soft coins with the edges already milled.
Time permitting, a fine jeweler's file could be used to add grooves.
