Is this stamp still valid?

[Connemara]

I found an envelope with a stamp on it in my closet. IIRC it's from last September. Is this one of the "good forever" stamps?

Yes. If a stamp says "First Class Mail" and has no price on it, it is a forever stamp.

Yep I have a bunch from when they were 32 cents and I'll hold onto them for a bit

Sell them when it costs $32,000 to mail a letter.
