The other variety of 1824/4 has the 2 and 4 much closer together.
From 1807 to 1836 these coins were "lettered edge". That is, the edge was not reeded; it was stamped "FIFTY CENTS OR HALF A DOLLAR". Unfortunately it's impossible to see that lettering in this PCGS holder.
These were minted in the millions most years and as there were no silver dollars struck between 1803 and 1840, many were used by banks to pay other banks; therefore many high grade pieces are available and prices are not exorbitant.
Note: All my coins are in a safe deposit box. I keep nothing in my home.
