The difference between the higher prices and the lower prices quoted for shares and stocks at the stock exchange is known as "jobbers turn."

Here's a simple explanation:

In the stock exchange, there are individuals known as jobbers who buy and sell stocks. They do not deal directly with the public but with brokers. Jobbers make a profit from the difference between the price at which they are willing to buy a stock (the lower price) and the price at which they are willing to sell it (the higher price). This difference is referred to as the "jobbers turn."

It's important to note that the jobbers turn is essentially the profit margin for the jobber, earned from trading activities. This is not to be confused with terms like commission or brokerage, which refer to fees charged by brokers for facilitating trades. Interest, on the other hand, is the cost of borrowing money, not related to the pricing of shares and stocks.
