In reading about langstroth I came across his price of queens (1863 )
Seems the dollar amount hasn't changes in hundreds if years
If it followed inflation,a queen should be 100 plus dollars
I guess Lang was taking advantage of cornering the market

What 20 dollars then would / should be today??

Langstroth received his first Italian bees at his home in 1863; Italian bees were more productive than the European bees that were most common in America at the time. He and his son sold Italian queens at 20 dollars each and in one year sold 100 of them, many being sent by post all over the United States
