You did put the coin posts you made in the wrong forum, one of the mods can fix that and if they do, you will be able to tell on your post. Not a big deal. They should be in the "US Modern Variety and Error Coins" forum.
I don't see that you ever made any other posts previously made by you, unless you had logged in under a different user name then? Only 3 posts as of this reply the two coin posts and this one I'm replying to now.
Replies to your posts will come like mine underneath, and you won't be notified, you need to check on them yourself. The numbers you are seeing are probably the read numbers not the reply numbers.
The way I use CCF (Coin Community Forum or this place) is I log on at the main page, then click my own name under the log in "Logged on as" to see my profile, there you will be presented with a list of the most recent posts you've made, I click on the one I want to see or right click and open several in new tabs if there are more than one post to check on and possibly reply.
Scroll down on your profile or any page at the CCF to see a list of the last 100 New topics and 100 Active topics links and around 20 individual post links below each of them, you can use to go right to. I don't use these that often, but sometimes when I've looked at all my usual areas.
Eventually if you stick around long enough and participate it will come as second nature, your photo postings came through just fine I see the photos and you have the coin upright and cropped as asked so that's a plus and ahead of many that start off as newbies here.
Your photos need to be vastly improved in quality of focus however to help in identifying errors and varieties or grades. There is no way to tell if a coin you show is a double die or not due to the fuzziness of the photo.
Try taking the photo only with a camera on a tripod or at least resting against something solid so as to reduce or eliminate shake. If you are using a phone camera then try simple things like a box of Kleenex or a large can to rest the camera on and if needed another smaller item to raise the coin up until it fills the screen, if possible lots of direct light and use a tripod release or your headphones (on most phones the shutter can be clicked by pushing a volume button on the headphone switch), that way you aren't touching the phone when the shutter takes the photo and no shake occurs. Sharpness and good lighting are everything in coin photos. See this comparison I made.
I shot this on my iPhone 8 hand held okay lighting cropped and saved in Photoshop at 72dpi high quality jpg to come in under 300KB limit.
Compare to tripod shot camera not touching the camera remote shutter:
Pretty obvious the difference in sharpness when the camera is completely steady when shooting and better direct lighting helps tremendously (I use a pair of Ikea $9 LED lamp on goose neck stands), nothing crazy expensive. Granted the coins are different, I used one I had already posted in the past I had in my upload folder, the handheld shot I just took now to make this post, same desk I usually am shooting on, same light (only one turned on though and not positioned as well as I do when I'm trying to take coin photos).
You should be able to see very easily the difference, if I ask you about the doubling on the "OF" in the top coin vs. the bottom coin. Which side is it on?
