The reverse has what appears to be metal pressed onto it. I know it's a rough looking coin but is this a strike through? It weights 5.63 g.
Looks like solder on your coin. Seems to be a lot of environmental toning as well. Not a strike through. Keep posting and searching.
First of all, 5 photos of the same shot isn't necessary, and you need to post photos FULL IMAGE so we can easily view and enlarge the item. When you have a substance that is raised on a coin, you might want to try a 100% acetone soak overnight and then use a soft object, such as a wooden tooth pick, to see if the substance can be removed. 100% acetone (NOT fingernail polish remover) will not hurt the coin or render it "cleaned," so it is safe. Your coin appears to be either glue or some other crud. Coins left in cupholders in cars often get soda and other stuff on them.
Ok. So, I don't really know what you mean full image. I take the picture then down load it from the photo gallery of my phone. It's hard to get the right lighting and angle for a good picture. You probably think I'm a idiot but if there is a better way I'm all in. Took me forever to figure out how to get them from the gallery to here. Now everyone is going to see this ugh. Well it is what it is I guess.
It takes time to learn this site so be patient and it will come to you. Ok at the files you attached to this post. Before you post they will look the same but just above the photos is a line that reads full image. That’s the one to click.
This is the nicest 1992 D I have ever seen. Found it coin roll hunting. How do you know when to send something to be graded? Would you recommend PCGS?
Looks more like some type of adhesive, epoxy, gum, etc. etc. etc (AKA Goo) is stuck to the surface on the reverse side.
Not worth grading. For modern coins to grade high enough to cover the grading fees and costs, it needs to be a MS-68 or higher. Not long ago I purchased a MS-68 1958-D Wheat Cent for $5.00 from my LCS. It just takes experience and that comes from time in the hobby. Take the time to learn and enjoy the hobby first. If you feel you have a coin that should be graded, put it in a 2x2 or a PVC flip and save it. For years if necessary. After you’ve gained the experience go back through them. If you find one or two that should be sent in, count your blessings.
Not to worry @Superloop, we all started in much the same place. Your later post with the cent photo is great, so you've learned already. You do need to click FULL IMAGE on each photo, not just the first one, or those will still be thumbnail size. Good luck and keep learning.
