What was the price of a loaf of bread in 1850?

5 cents. Actually most people made their bread in 1914. White bread as we know it didn't yet exist. So, the cost of roughly 5 cents would be for a loaf of bread from a bakery. But consider ...

In 1914 the average work week was 49 hours and the average weekly earnings were $10.92; the average wage per hour was 22 cents. So you could buy 4 loafs of bread for an hours work. If a loaf of bread from the bakery costs $3.00 now then a wage of $12 an hour would be compatible (allowing one to buy four loafs of bread for an hours work).
