COIN is a Canadian one-cent piece. They made them this size (size of a qurter or an English halfpenny) from 1858 through to 1920. Composition is Bronze: 90% copper, 5% each Tin and Zinc. Expensive stuff. That's a nice one. Interesting to know what date (it's on the back). It is replacing, likely, a later Butt Marking Disc which has been removed.
The RIFLE it is on is a Martini-Enfield in calibre .303. The thing that looks like a star is 2 Broad Arrows nose-to-nose: Sale Mark. It has been legally Sold Out of Service. The "E" on the barrel flat identifies the rifling inside the barrel as ENFIELD rifling: 5 lands and grooves, equal width and deep grooves: lasts about 5/8 of forever if you're careful with it. A Martini has the quickest lock time of anything ever built: that`s why they are still being made up as Match rifles and used in the Olympics. This one originally had a barrel with HENRY rifling and so was called a Martini-HENRY, but it is called a Martini-ENFIELD now because of te barrel change.
The Jap carbine is a Type 38 (says so on top: they stole their numbers from China) which means that it is well-made and it takes 6.5x50.5 SR ammo, also called 6.5 Jap. Norma makes it or you can make your own brass by sizing and trimming .220 Swift. The rifle was designed by a fellow named Arisaka, who really knew what he was doing. The rifle is basically a Mauser with some very real improvements. The split stock was made that way: they didn`t have much big wood for making stocks, so they built them up, all of them, several million of them. These can be scary accurate.
The straight-pull is a von Mannlicher design, model of 1895. This was the official rifle of the Habsburg Empire, also called the Austro-Hungarian Empire. It took in modern Austria, Hungary, Slovakia, Czech Republic, part of Ukraine, Bosnia, Herzegovina, a bit of Italy, bits and pieces of much of the rest of the map of Europe. It was BIG and it was ruled by Kaiser Franz Josef I, who actually was a very good Emperor and very much an expert on military weapons. He personally tested any weapon that his Army was thinking about using. The open-sided CLIP was in Service BEFORE World War One: it is pictured in the 1909 edition of the TEXT BOOK OF SMALL ARMS, which was the British Army`s guide to world small-arms and what makes them tick. The closed-sided clip was issued with the 1886-series rifles, I believe. I have an open-sided clip here with a crowned double-eagle on the back, so it is definitely Imperial.
Your semi-auto rifle is definitely an AG-42B. It s gas-operated, throws the brass half a mile, likely is the most accurate semi-auto ever built anywhere. You CAN slow the brass down so that it doesn`t wreck the empties. I DO HOPE the mag has been pinned to 5 rounds: this is a FREE COUNTRY where you can`t have the rifle as it was built, Comrade. By the way, the `SS` on the left side of the receiver does NOT mean that it saw service with the Nazi SS: instead, it is the initials of the man who inspected the rifle when it was built: Sten Stenmo.
You have the start there of a GREAT collection.
BTW, likely you will want to load your own shells for all of them. It`s fun, it`s a LOT cheaper than buying factory ammo AND you end up with better ammo becaus you can suit the load to the individual rifles.
Have fun!
Hope this helps.
