Re-slabbing NCG Copper Coins

I’ve seen posts about the NGC copper coin 10yr expiration but I’m curious, has anyone here ever sent an NGC copper coin in for reslabbing? I am curious about hearing peoples’ experience with this, and am also debating whether to send more valuable NGC graded copper slabs to PCGS, since their statement about copper is more nebulous (e.g., they don’t guarantee continuity red or rb designations but pcgs-graded copper coins don’t automatically turn raw after 10 years)

I always “buy the coin not the slab” but also don’t want needlessly allow coins to lose due to my own laziness in letting NGC grades expire…
