The image is a slide from a presentation on manufacturing techniques. It is titled "Manufacturing Techniques" and is written in black text on a beige background. The slide is divided into two sections. 

The first section explains that from the 8th century BC to the 6th century AD, most Chinese bronze and iron coins were cast from moulds. The casting technique using single-layer molds that used to be common was replaced by the more advanced superposition casting method around the 1st century AD. The sand-box method first appeared around the 5th Century AD and replaced the mould technique in the 10th-century AD. In the late 19th century, a trend toward machine minting emerged.

At the bottom of the slide, there is a brief description of the manufacturing techniques mentioned in the slide.
