i created a cylender and enlarged it i then hollowed out the cylender and created a slot for coins to go in throughi then created a lid to go on the coin collecter.
For starting create a cylinder and enlarge to a preferable size then creat a coin slot a little bit larger than the coins you are putting into it then create another cylender use that to hollow out the first cylender and then you can create a lid.
this is similar to what i wanted my coin collecter to look like
