It depends on condition. At an auction I just attended, I saw a lot of five knives with sheaths including a n old bayonet sell for $100.
200 dollars
Probably $200 or more, depending on it's condition..
the top 'bayonet' appears to be ww2 Japanese rifle bayonet the bottom 'bayonet' appears to be an early US 1903 bayonet or british bayonet. message me with writting on bottom bayonet, on blade near top of hilt.........
Sorry- but a bayonet for WHAT? You told us the year, but not what rifle it is meant for.
$10.00 to $40.00 depending on grade
Average retail value: $1.00-$3.00
its around $15-$20. There is no such thing as an M8A1 bayonet. The M8A1 is the designation of the scabbard that holds the M-4, M-5 (series), M-6, and M-7 bayonet.
The US .
However much people will pay you for it.
US springfield 1903 and M1 garand of WW2
US Cognac was created in 1899.
It depends on what bayonet you want. A 16 inch blade US bayonet that fits a M1 Garand or 1903 rifle in nice shape will run 250 dollars and up with the original scabbard. A spike bayonet that would be correct for a british rifle can be had for 20 dollars or less. There are hundreds of bayonets that were used in WW2 prices vary depending on rarity and desireability
