I know they sell mason jar coin lids on Amazon. I think they're like $10 for a set of 6...hope that helps!
You can find plastic screw cap lids for mason jars at Walmart, no need for the metal ones. For the coin slit, use a hot Phillips screwdriver and melt your way through.
Hi Martha: Make a mark on the outside top of the lid, get a piece of wood that fits into the lid, where you want the hole to be. Place the whole thing on something sturdy and then pound the mark with a regular screwdriver and hammer until it makes a hole where the line is, about 2" long or however long a quarter is plus a little bit. The wood keeps the lid from bending inwards. Once you have the hole, remove the piece of wood, and bend the sharp edges that are on the inside of the lid to the sides so you have an opening for the coins. Using the hammer, pound the sharp edges that you just bent, over onto the lid of the top, making the opening smooth. That should do it :) Easy peasy, as they say :) Good luck
Hi! Hope this helps!

Remove the lid and place it on a scrap piece of timber. Punch a slit hole in it by using a chisel., When gap is wide enough, turn lid over and knock flat the raw edges for safety using a small hammer. Happy saving........
Stab it with a knife and fold any rough edges below. You could also add some tape to cover any shape edges.
Martha: maybe these will help
Remove the flat and then you can cut a hold in it. Make sure to cut from the top so the edges are pushed to the inside of the jar. Replace flat and ring.
You can use a flat head screw driver to make a slit in the top, Turn the cap over and make sure there are no sharp pieces.
