The British had money with actual real value to it.
very rare Canadians with no US mark ! 2500$
They reacted by quickly inflating their money supply, in turn debasing it's value, to pay for the war.
A WWII German sniper rifle is at once VERY rare. If you chance upon one at a gun show, depending on the condition of the piece, it can fetch at least $1,500. And THAT would be the low-end price for a Mauser KAR 98 (bolt action) with an original scope in perhaps rough condition. You would have to be very careful that the rifle itself had the original scope (Zeiss optik, or Henseldt type) matched to the rifle. Now the rifle itself should also have matching numbers on every piece in order for the value to be justified. There have been numerous post-war-to-present Mausers fitted with scopes and the unwary buyer not knowing this can purchase a "re-conditioned" Mauser fitted with an original German scope, but the value of such a rifle will be reduced as that sniper was not truly original. I have seen these going for $1,300. But an original GI bring-back in above average shape and un-tampered with will bring upwards of $3,000.
The value of one British pound in 1918 was approximately equivalent to its face value. However, the purchasing power of that pound would have been significantly higher compared to today due to inflation over the years.
50-300 or so
Ive seen them fo £30 to £40
50-150 or so
50-500
100-1000 USD depending on specifics
Need to know a make, model, and description of the stamps. The British used more than one service rifle during that time.
50-500 USD depending on condition, variation, accessories, etc..
50-150 USD or so
Assuming you mean a British MILITARY rifle, such as the SMLE, between $100-$350, depending on condition and originality. Rifles that have been "sporterized" lose much of their value as a collector's item.
50-180 and 50
Sorry- but a bayonet for WHAT? You told us the year, but not what rifle it is meant for.
No way of telling without knowing what make and model the rifle is, what condition it's in, and what country it was manufactured in.
