I've been following the prices on Iraqi helmets... and let me tell you, they are quickly digging deep into the category of "high end" militaria. While the fairly common M80 helmets (and their later Iraqi made M90 and M90/03 counterparts) are typically under $100, there are others that are selling up into the 4 digit range. Furthermore, desert tan painted M80 helmets with painted insignia are also selling for hundreds of dollars. Check these out:
Iraqi PASGT style helmet- $1,009: http://www.ebay.com/itm/Iraqi-Army-issued-helmet-/330676048883?pt=LH_DefaultDomain_0&hash=item4cfdd413f3#ht_500wt_1204
Iraqi M80 "Medic" helmet- $500: http://www.ebay.com/itm/Iraqi-Medic-Helmet-Gulf-War-1-Desert-Storm-Military-Bring-Back-Rare-/160721879079?pt=LH_DefaultDomain_0&hash=item256bc54027#ht_1103wt_956
Iraqi M90 helmet- $100: http://www.ebay.com/itm/IRAQ-GULF-WAR-IRAQI-M-90-Combat-Helmet-Near-Mint-/130637641269?pt=LH_DefaultDomain_0&hash=item1e6a9c3635#ht_514wt_1189
Just thought it was interesting to see the high bids some of these helmets are fetching... Obviously, the uncommon variants (like the composite PASGT type helmet above, the Fedayeen helmets, earlier Iraqi made Kevlar PASGT type helmets, etc.) are fetching the super high prices, but as noted, even the common helmet types are starting to exit the realm of "affordable", especially when they have some painted insignia on them.
Makes me feel bad I didn't win a really sweet Iraqi made PASGT type helmet off Ebay a while back... it had an old USGI 6-color desert cover on it so it looked like a standard US PASGT helmet unless you looked closely. Sold for a bit over $200.... sigh.....
