These playing pieces were fragile, and since not many were produced they became collector's items.
In the United Kingdom, some sets used wood pawns from the game "64 Milestones" as tokens, but the majority were cardboard cut-outs slotted into black wooden bases.
Metal was needed for the war effort, so wood pawns were used for most "Monopoly" pieces during that time.
These were the standard pieces until the 1960s when the pewter tokens replaced them.Later in 1935 the race car purse was added to the 7 token sets and then in about the middle of 1935 the purse was added to 8 token sets.In late 1935 and early 1936 the lantern and rocking horse were added to 10 token sets, these peices are especially hard to find nowadays.The first pieces, from 1935 to about 1938, were made by the Dowst Manufacturing Company, makers of "Tootsietoys." These were die-cast from zamak, a zinc alloy also known as white metal, monkey metal, pot metal or die-cast zinc.
Impurities in the manufacturing process caused some of them to oxidise and turn black.
Standard editions, however different they are, usually use pewter tokens.
