As Mr. S. indicated, what appears to be tokens of similar style are on tokencatalog.com - Kiser's NM book lists nothing for that state, but Pritchard's CO book has #DE1055 in Denver in 10¢ and 50¢ denominations. Pritchard does not indicate that the lettering is incuse, but he does say "uniface" which is to be interpreted as there is no lettering on the reverse - like yours. Pritchard states the initials are for A. H. Jones & Co. - The Cabinet (Saloon) - 1883-92.
