I use aquarium gravel, the small stuff, soap, water and a lil ammonia.

I'm not sure of the exact size of aquarium gravel that I use but here is a picture of what I've been using for the last 5 years. There are some really small rocks in it and some that are a little larger.
I use a dual tumbler from Harbor Freight and I fill one of those cheap clear plastic cups level to the top with coins. You know, the kind of plastic glass that they serve a mixed drink in at a not so high class wedding. ha ha ha
I dump the coins in the tumbler and then fill the tumbler almost to the top with the aquarium gravel and then put in a tablespoon of Dawn and I fill the tumbler up with water until it reaches the the seal. I typically tumble the coins for 12 hours and between 6 and 8 hours into it I dump the sludge out and put another tablespoon of Dawn in and fill back up with clean water. Tumbling any longer does not make much of a difference and depending on how fast your tumbler runs, 12 hours may even be a little long. You'll have to experiment with what works for you but that should give you a good start.
I've made it an annual event to tumble my coins which will be happening any day now. When I'm all done, I rinse the gravel really good and then leave it sit in a big tray next to the wood burner stirring it every few hours to dry it out and then I pour it back in a big container that I bought at he dollar store. Be sure to tumble your pennies separate from the other coins, if not then your quarters, dimes and nickels will come out a reddish brown color.

Be sure to get the "natural" colored gravel, not the pretty colored stuff.

I use walnut shells dry. Any kind of rock tends to take some of the material. I bought a large box of walnut shells at Harbor Freight because I also use it to finish rock polishing.
