i would say a couple hundred dollars
sounds like a pre-WW1 Springfield 1903 rifle bayonet
Sorry- but a bayonet for WHAT? You told us the year, but not what rifle it is meant for.
How long is the bayonet? If the blade is long, (14" +/-) it sounds like a very early year Springfield rifle bayonet. If it is 10" long, it may be a WWII cut down model. IF the former, $250.00 or more, if the latter, $125.00. Condition (good or bad) can change values by 50% or more.
Dates to 1908. Value depends on condition and how original it is. Range from 300 to multiple thousands.
its around $15-$20. There is no such thing as an M8A1 bayonet. The M8A1 is the designation of the scabbard that holds the M-4, M-5 (series), M-6, and M-7 bayonet.
Your inland made M-1 Carbine will sell for between 500-750 dollars,depemding on condition and a good bore.
very rare Canadians with no US mark ! 2500$

No US $1 coins were struck in 1908, look at the coin again and post new question.
If uncut and with the scabbard, between $150.00 and $300.00, all depending on condition.
You are going to have to be a lot more specific. You need to tell us the denomination of the coin and condition if you want to know the value. All you've told us is you have a British coin from 1908 with Edward VII on it.
