The Force, have you ever licked your thumb and rubbed a coin to see the date better ? You cleaned it. Take an old cent and rub it with your T-shirt. What have you done ? Well you've made it look much better since you took off all the dirt, and the cotton won't scratch bronze so you didn't harm it, but you cleaned it.
I'd bet that 99% of the collectors on this site have coins that have been cleaned, one way or the other, and even many slabbed coins have been dipped. I remember reading in the Canadian Coin News or on the defunct CCCS coin site that there was a Canadian collector who owned a 1936 Dot dime which was graded as ICCS-65 and had dark tarnish. It was dipped and regraded to 66 with no remarks.
A dip is not like polish. It removes the silver oxide, basically a type of rust. It's like dusting your mahogany dining table with a dry chamois, not a dish-rag and Pledge. If not removed, sometimes the tarnish causes pitting. Silver in slabs and flips can tarnish on their own if there was some moisture sealed in. Sent through the mail in winter at -20 to a warm house can cause a start to problems in slabs. How many times have you seen slabs or flips with RED for the cent but now they're not really full red now ?
The slabbed one should stay in the slab. IMO it looks a bit less than MS-63.
Give freedom to the ICCS 50 cents and dip the darn coin in TarnX for 15, maybe 20 seconds, TOPS (pour some in a small glass, swish around), you can rub lightly around the edge with your finger to help a bit, then rinse with lots of water, dry it and let it return to room temperature before putting it in a 2 x 2. You can return the liquid to the bottle and reuse. If the coin doesn't come out better-looking than in that flip, then I'll send you a silver dollar like the 1966 I posted earlier. And when you show your new raw 50 cents to your collecting buddies, they will ALL go "WOW". And they'll have no idea it was dipped.
