Can probably be done in persistentcharacters.meta file.

It is from the Disable Horse Holstering mod. It is meant to be replaced by the rifle holster, but you do not have the Rifle Holster mod installed. The Enable Back Holster needs to be set to 0 in the .ini for the coin to disappear.

There are a few youtube tutorials on how to do that.  One of the tutorials: 

Most npc clothes do not fit on Arthur. Lots of clipping and they are lower quality so not really worth the time imo. If I remember correctly most clothes from online fit together with most of the npc heads so that is something that could be mixed (arthurs head only fits with some of the online clothes). Hats on npcs only fit from singleplayer...

You can try your luck with YMT Unhasher: https://www.nexusmods.com/reddeadredemption2/mods/951

You just drag your .ymt file on it and it will unhash it and create a new unhashed file. Lots of hashes are not known yet though...

I made a mod like that that I am using and it also disables honor notification. It is not perfect though cause I did not figure out how to disable description only for these two so  now every item I loot only shows up as a picture and has no description to the left of it.
