Absolutely. Every day.
I review quite a few Neil Armstrong signatures. I always date the item if possible. This is because his signature changed significantly over time. Certain items he stopped signing at certain times. This all creates more opportunities for forgers to make mistakes.
I can't tell you how many times I've seen an 80s or 90s style signature on an item he stopped signing in the early 70s. Or a 70s style signature on an item that dates to 1993. Truth be told, the signature is almost always identifiable as a fake anyway, but it's nice to have the extra nail for the coffin.
