The latest batch includes one mailing from every group of ten stretching from the #90s to the #190s. See the whole list here. Each is filled to the brim with rare Howardiana. Some folks got some incredible deals in the last batch, scoring large and notable mailings for a relative pittance. #118 and #176 especially were great steals at those prices. The auction for #100 got a bit ridiculous price-wise, but it is indeed a rare-as-hell mailing and the biggest in the a.p.a.s history (plus it contains Don Herron’s infamous “I piss on you all from a considerable height” smackdown, a legendarily hilarious moment in the a.p.a.s history), so perhaps over the long-term such a buy will pay dividends. The winner now has a mailing that even several hardcore REHupa collectors still are dying to find, so they have that to weigh against the price-tag.
My personal view these days is that anything under $50 for an old REHupa, and anything under $30 for a new one, is a good deal given their long-term rarity and the amount of collectability they have. For information on why REHupa mailings are rare, collectible, and an essential cornerstone of any good Howard collection, see here.
