Please Help Sweeden Coin

Other than the number and letter are their any other markings, hall mark, date, ect...? Are they all the same size and weight? I'm thinking that it might be a coin weight rather than a coin.

Sweden did make copper "plate money" (platmynt in Swedish), in the early 1600's; it normally looks like this, with five round denomination stamps in the centre and corners. Sweden issued these large copper "coins" because they owned a large supply of copper, but virtually no silver or gold. These platmynt therefore served as "copper bullion"; the theory was that the platmynt were deposited in the bank, and a banknote (one of the earliest banknotes in Europe) would be issued to circulate in it's place. The system didn't work (people didn't trust the paper money, which was easily counterfeited) and the playmynt were melted down and sold for scrap.

However, while your items look superficially similar, they're not officially issued platmynt. What they actually might be, I can't say for sure. If they're numbered from 1 to 10 but they're all the same size and weight, then the numbers can't be a "denomination". I suspect they may have been some kind of worker's check or tally token, used in a small factory. Or perhaps game pieces of some kind, sort of like metallic playing cards.
