This is a 1957 1/4 of a shilling, from the Bailiwick of Jersey. The obverse features a crowned portrait of Queen Elizabeth II, and the reverse the coat of arms of Jersey. This coin is composed of nickel brass, and my example weighs 4.64g.
The 1909 Russian 10 Kopek is a small silver coin minted during the final decade of the Russian Empire under Tsar Nicholas II, the country's last emperor. Struck in 50% silver at the Saint Petersburg Mint, the coin features the majestic double-headed Imperial Eagle on the front and its denomination wrapped in a laurel and oak wreath on the back. Because over 25 million pieces were produced that year, it remains a very common and highly affordable piece of history for collectors, often valued at around $4 to $10 USD in typical circulated condition.
