Well a few methods you can check your own coins:

>Ping test
Silver has a very specific ring to it, go ahead and test that. You can find the sound all over the internet, it's very different than the sound a clad fake would make
>Neodymium magnet
If you slide one across a silver coin, it should slide off somewhat slowly. So not entirely attracted, but also not so attracted it sticks. See gif related. No it's not slowed down.
>caliper
Check to make sure your coin/round is the proper diameter/thickness.
>rim
This one is an instant spot. If the coin has a reeded edge and shouldnt, for example, you know immediately that its counterfeit.
>Weight
Probably the most common check. If it's over the official weight, it's 100% counterfeit. If it's only a bit under, then it may be counterfeit. However, some really worn coins can be significantly lighter due to the wear.
