An Egg Scale was used by the storekeeper in the general store in the late 1800's and early 1900's to grade and weigh eggs that the villagers hoped to trade. The scale told the store keeper the egg's size and how much it weighed, and he or she would decide if it was a worthy trade or not. (The storekeeper also checked the eggs for freshness.) If so, the store keeper would take the eggs and give the villager the item he or she wanted. The only problem with the Scale was that it could only weigh one egg a time, so if the villager had two dozen eggs, weighing them would take a long time. The egg scale was made out of metal with a wooden base.
