If you take a look on the letters ONE DOLLAR has a raise looking ring first I was thinking PMD and heat but that raise bump can't be done by heat

You didn't show a picture of the reverse so can't comment on the words ONE DOLLAR
but the obverse is just badly damaged with a swelling caused by heat.

I wonder why you say this @4q. Do you have some knowledge about the metallurgy maybe? As a general rule, we always say that coins exhibiting this sort of large bubbling are damaged by heat (so-called campfire coins). Your coin is badly damaged, but it would be good to know if there is some damage other than heat which causes that bubbling. Thx for explaining your reasoning.

Looks like heat damage among other things. Is it just me, or does that baby's head look like a skull?

Heat damage, PMD.

88.5% Copper, 6% Zinc, 3.5% Manganese and 2% Nickel. Seem to has some acid interferences, and some heat also. Probably was heat and then acid. At the surface left Cu and Zn.

That Sac has had a rough life. PMD - Environmental Damage by some form of heat source causing the bubbling. The coin's physical makeup is a three-layer clad construction - pure copper sandwiched between outer layers of manganese brass which may have been worn away. Seeing a photo of the reverse and also the edge of the coin would help. I also see a mumified corpse for the baby's head similar to what coinfrog sees in a skull if you look at the forehead as the face, and maybe a tumor on the head like they have been exposed to radiation. While its not an error, I always wonder if there are collectors out there who buy or retain these type of oddball coins that come up.

Edit: This is all I could find. The Sacagawea dollar may be referred to as manganese-nickel, but it is actually comprised of 88.5 percent copper, 6 percent zinc, 3.5 percent manganese and 2 percent nickel; the copper-zinc-manganese-nickel mix at the surface has significantly less copper than at the core of the planchet. The surface toning that may result could follow the pattern of toning on brass or copper. With improper storage or improper manufacture of the planchets, it is possible the center copper core could "erupt" and react in a similar manner to an ancient silver-coated copper fourree, eventually causing a bubble to rise to the surface of the coin. https://www.PCGS.com/news/color-of-...deeper-tones

Yes, it can. Clad coinage can form "bumps" and "lumps" exactly like this, when the plating splits away from the core due to the heat and an air bubble trapped between the two layers expands and pushes up the softened metal.

The other option is pinhole damage to the clad layer allowing a corrosive substance to seep into the core and corrode it. The end result can look the same - a raised "lump" - only the "lump" in that case would be filled with corroded metal rather than just air. However, I think the first option is more likely in this case.

It's just a beat up coin...any defiling action was Post Minting Damage ( PMD)...regardless of the actual causation...not sure too many people have a collection of PMD coins...sub-classsified.

A full, sharp image of the reverse might tell us more.
