I dumped all (over 500) of my LE chips, except for the ones that really meant something to me. Your "focus" though, was far more refined than mine, When I started out, I just pretty much accumulated, rather than collect. If it is still important to you to own the most comprehensive collection in that class, keep them!

I don't think I will ever purchase another LE though, unless I REALLY like it. I like the "history" an old house chip represents to me.
