Gather a wooden box that measures 12 inches x 8 inches x 1.5 inches, one wood piece that measures 12 inches x 8 inches x 1.5 inches, one wood piece that measures 12 inches x 8 inches x .5 inch, felt, glue, a tape measure, a pencil, a reciprocating saw, wood stain, sandpaper and tack cloth. Make sure that the two pieces of wood fit snugly inside the box.
On the 1/2-inch-thin piece, make a measurement 2 inches down on either side of the 8-inch width, and then draw a line between the marks. Draw two more lines at the 4- and 6-inch marks. Mark points at 2-inch intervals along each of these lines, showing where to make the holes for the coins. Center the coins on these marks, and trace them with a pencil. Use a thin blade saw to make the holes, and sand them to smooth out the circles. Use a tack cloth to remove excess sawdust. Stain the wooden box and the piece of wood with the holes. Cut a piece of felt 2 inches larger on all sides than the 1-inch-thick piece of wood. Apply glue to the felt, and affix it to the wood piece without holes. Cut another piece of felt that's the same size as the inside of the lid, and affix it to the lid. Put the felt covered piece of wood in the box felt-side up, place the other piece of wood on top and place the coins in the holes.
