Most of the post-WW2 Garands were produced after the Korean War with peak production in 1954-55. In general the post-war Garands tend to be in better shape with more original parts than the wartime rifles, most of which went through one or more arsenal overhauls during military use.
There are 2 Springfield Garands of 1954 and 1955 production still listed on the EE which have now been sold. The asking price was $1300 each. These look to have been from the lot that were being sold at retail in the 2007/2008 timeframe. These included post war Springfields, IHCs and HRAs with a sprinkling of WW2 rebuilds as well. I believe that they were surplus from either the Saudi National Guard or Jordan judging by the fine "sands of Arabee" that could be found in the internals. As a group they were in not too bad condition and I bought a number of them. All showed original finish and some mis-matched parts of mostly post- WW2 make. Wood was pretty much toast or replacements and there were a number of broken and unserviceable parts. Most barrels were good, altho I did get one that was bulged at the muzzle at a discount. I lucked into a nice takeoff barrel of the correct vintage which I installed as a replacement. A lot of the parts needed re-Parkerizing, but all in all they were pretty good value for money. I was able to find a couple of scarce variations among them incl 2 IHC rifles built on SA and HRA receivers which were supplied to IHC on contract.
It seems that the baseline price for any decent Garand of any make or period(good barrel and wood and no rust/pitting) is around $1200 nowadays. You can add on more for those in better condition, especially for rifles with original receiver/barrel/stocks and correct parts combinations. Wartime Winchesters and Springfields command a premium, all things being equal, followed by the post-war IHCs, HRAs and Springfields. IHC produced the fewest rifles of any of the US makers. Many IHCs wound up in Iran as military aid in the 1950s and are not likely to return. I believe that Morocco also got a bunch of IHCs as military aid. The Breda and Beretta build/project rifles that folks are playing with nowadays are basically worth the sum of the parts used to put them together. Original parts-correct Breda and Beretta rifles are quite scarce and should command a premium as well, assuming that they remain in nice overall condition.
It's tough to pin down absolute prices on Garands as it depends on the condition of the individual piece as well as the preferences of the individual buyer, but I'd peg $1200 as a reasonable baseline in today's market. Two things are for sure; they aren't making them any more, nor are they importing any more of them. I'm taking an armful of various makes down to the big Chilliwack show next weekend so should have the chance to fine tune my price estimates after that.
