The Model of 1955 became the Model 25 in 1957 when model numbers were assigned. It became the 25-2 in 1962 but was still often called the Model 1955. The Model of 1950 was similar but with a lighter barrel. They are numbered within the N frame line. In 1955 the N frame serial series was 6 digits after the S prefix and remained so until the S series changed to the N series sometime after S333,000 or so. In 1970 the serial range started over at 1 with the N prefix. As I recall N1 was a Model 28-2.
There are also approximately 1000 Model 25-2's in the N330000 range that were made in 1976 that were mistakenly marked Model 1950 instead of Model 1955 on the barrel. As Saxon Pig mentioned, the Model 1950 had a slimmer profile barrel so when you see one of the mis-marked Model 25-2's with a heavy barrel, it's pretty obvious.
The 45 Colt version is the 25-5 and is a separate gun.
With condition being king (after scarcity, IMO) an unfired gun naturally commands a premium. IMO an early 1970s era 25-2 in very high condition will likely sell in the $500 range.
Was the miss-mark for both the 45LC and the 45ACP? Or was the slimmer barrel 45ACP only?
The mis-marked guns I referred to were Model 25-2 Model 1955's with the 6 1/2" heavy barrel profile chambered in .45 ACP. The story is that the incorrect roll mark stamp that said ".45 Cal. Model 1950" was used on about 1000 barrels before the mistake was noticed. As S&W had not made any Model 1950 .45 ACP revolvers (the rare Model 26 was the last) since 1960, you have to wonder why the roll mark stamp for the Model 1950 was even still out in the production area 16 years later !
My experience is that the 25s were never as popular as the Magnum caliber guns. I am shocked at the suggestion that a beater 25 would bring $700.
OK, I'll take $1,200 for this one that I bought for $375 a couple years ago.
