Just found this 1982 penny with something going on under the 9. It's got a small dot on the top of the 9, one right under it and two dots under the beginning of the 9. There is also a dot on the right side on the 1 and a little dot on top of the 8 and the 2. Could these all be cuds?
No look at all the irregularities of the surface on and in front of Abe. Don't just get "locked on" to the date. Look all around. Look at teh evidence of what is occurring from looking at all the problem across the entire surface of the coin. This is a "zincoln" or zinc core with a 8 micron thin copper plating. The zinc core is causing a lot of surface damage. such problems such as: https://www.coinworld.com/news/us-coins/2016/08/unexpected-bumps-on-coins-surfaces-vary.all.html 5. Plating blisters Plating blisters develop in the coin in the immediate aftermath of the strike, as gas expands between the core and poorly bonded plating. Among domestic coins, plating blisters are the exclusive province of copper-plated zinc cents. Blisters are generally small and subcircular, with a smooth surface and soft outline. They can occur anywhere on the field and design. The design continues uninterrupted as it crosses a blister. 6. Occluded gas bubbles Solely the province of solid-alloy coins, occluded gas bubbles form just beneath the surface and push up the overlying metal immediately after the strike. Like plating blisters, the surface is smooth and the edges soft. The design is uninterrupted. 7. Corrosion domes Contaminants trapped beneath or penetrating the surface of aluminum, plated zinc, and plated steel coins can react with surrounding metal to form an expanding front of spongy, corroded metal. The resulting solid dome will superficially resemble a hollow plating blister or occluded gas bubble. In many cases the corroded metal bursts through and may fall out, leaving a crater.
FYI, Die Chips occur on the inside areas of the coin. Cuds, are essentially die chips on the rim/edge of the coin. You'll see die chips more common on letters such as an "O" that the die has a little pointy part to make the inside of the "0"; and that pointy part breaks off. Or numbers with an enclosed area. Thus the reason you see 9 that are fairly wide open in the curl which never closes the circular part of the 9, to increase die life and reduce die chips. But die chips can occur anywhere.
