Who knows who drives the prices up? 20 years ago you could buy a No. 5 bayonet easily for $25 - $35 when they were available, about the same as you paid for a US M1905 bayo for the '03 Springfield. Of course at that time you could find M1917 and P13 bayonets literally by the bucketful at any flea market and you didn't even consider paying more than $12 for them IF they had the scabbard. Without scabbards they sold for no more than $9. P07 bayonets went for the same.

Time marches on.....
