Luckily for us the Soviets cranked out millions of 91/30's, they are the cheapest Mosin right now. There were fewer M44's made, relatively, but they are still "common". I love how some dealers are asking $3-400 for refurb M44's now, saying they are "rare". Just because the fresh imports of M44's have stopped doesn't make them rare. I was seeing M44's for $60 back in 2001 or so, I just didn't buy many of them.
The Mosins are so cheap because most shooters don't find them "refined" enough and unfortunately many people buy them and hack them all to pieces to make them into cheap deer guns. They are often the cheapest gun at the gun show, and are bought as beaters and truck guns.
In 20 years 91/30 refurbs will still be cheap, there are just SO many of them out there. Imports are still coming in, and the refurbs will never be "collectible".
Now, the rarer stuff has shot up in price, again I recall seeing SA marked 91/30's and 91's at gun shows for $100, I bought a few of them. 10 years ago the SA marked Mosins were nothing special, it was "just another property mark" and then interest in the Winter War and Finnish Mosins went up and the SA stamp started to carry a premium.
Century used to have M91 and 91/30 U-Fix-Em's for $20 each, a lot of them just had cracked stocks. Those days are over.
Things change, 20 years ago Mosins were rare in this country, and collectors paid a premium for the Soviet rifles. Remington M91's were cheap years ago, because a lot of them never left the US and Bannerman bought a bunch of them and hacked them up, and converted some to 30-06.7.62x54r was an oddball round no one had heard of in the US, kind of like 7.62x39 was.......now the stuff is everywhere, along with rifles that fire it. Now a minty, matching Remington M91 with no SA stamp or import mark can bring over $1,500. An older guy told me he paid $700 for a non-refurb M44 in the 1980's, you just couldn't find many here, and most were Vietnam bringbacks.The gun market does strange things sometimes.
