Bear in mind, that in 2002, Canadian 10-cent coins were struck on multi-ply nickel & copper plated steel planchets. If it was struck by 1-cent dies and collar, then I would expect the rim not to be reeded (2002 Canadian 1-cent coins have smooth rims). This looks like a 2002P 1-cent coin, struck on a 10-cent planchet. They are uncommon, but by no means a rarity. Some years are more common than others (e.g., 1979, 1995) and the price of the error is reflected by that. 1-cent coins struck on silver 10-cent planchets (before 1968) are much rarer, and costly. Lastly, the Canadian error market is nowhere near as strong as the US market. If your coin is uncirculated, you can expect to get about $150 to $250 for your coin from a 1-cent error collector (a dealer would offer less) the actual price depends on the grade. Less for MS-60, more for grades MS-64 or better. Circulated examples (AU) are worth around $75-$90.
