It isn't a coin, it's a charm. Genuine "Chinese cash style" coins almost never have pictures or images on them, and the one exception has a horse, not a turtle.
It isn't old, either - it appears to be machine-struck, rather than sand-cast as cash coins traditionally were.
The inscription on the obverse, read in the traditional up-down-right-left order, is "Ji Xiang Ru Yi" , literally "good auspiciousness comparison-with ideas" but more poetically translated as "May your good fortune be according to your wishes" or even more poetically, "May all Your dreams come true".
The little holes drilled into the rim at top and bottom are for mounting the coin onto a wall or some kind of Feng Shui decorative piece.
I haven't found an exact match on zeno.ru, but I did find several examples of Ji Xiang Ru Yi charms - it was a popular saying back in the Ming and Qing Imperial eras - including
this item with the exact same inscription, style of writing, machine-struck appearance and similar top-and-bottom drilled holes. The piece is described as a "modern tourist souvenir".
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
