The first two rings are silvered brass and the second two are brass. The first two both read on the top "New York World's Fair." While their designs are very similar one shows only a partial sunburst and the other shows the full circular sun. This one has tiny letters "NYWF" on the bottom edge whereas the other does not. The one with the partial sun has lost some silver flashing mostly from the sides but overall Fine and the first is NM. Both have expansion bands as do the following two with brass oval tops. Again these have similar but different designs. Both read "New York World's Fair." One has the date "1939" on bottom edge and one does not. Each also has differences in the depiction of the sunburst and the ramp area to the left of the Trylon. The one without the date has Exc. luster while the one with the date has a rather dull brass finish all over.
