The task that you have set for yourself is a field of photography known as Macro Photography. I suggest that you do web searches for that phrase.
One reasonable explanation for your blurry photos is when you focus very close to the lens, your " depth of field " become very short. Do a web search for that phrase, too. I suggest that you visit DOFmaster dot com, and look at their tables.
I think that you are simply climbing the learning curve of macro photography. You may need to use a technique known as photostacking. This is where you take several photographs of an object, each shot focusing on a different part of the object, and then the series of shots are combined through software.
That shot is comprised of 10 separate shots, each focused on a horizontal slice of the coin.
I read some info that you suggested. I am not taking photos up that close. I design jewerly and need to take photos of my creations to put online. This is only some of the photo as it is too big to post. But see how some is clear and some of the photo is blurred? That is what I am trying to figure out. I am not talking about micro marco photos, just photos of necklaces. Thanks

Waddizzle urged you to read up on "depth of field", so I'll assume that you did that. In that picture, the difference between the distance from the camera to the lower part of the necklace and the distance from the camera to the upper part of the necklace exceeds the depth of field of that lens at that aperture. That's why the upper part of the picture isn't in focus. If you want the whole picture to be in focus, you will have to position the necklace and the camera so as to correct that situation. Use of the word "macro" (or "micro") in the description of your problem or its solution is entirely optional.

Bob, is correct about the DOF, depth of field, working against you. Your shot is excellent. The laws of physics are working against you, making it almost impossible to get the entire jewelry piece in focus. This is due in large part to the proximity of the lens to the subject.

The link is old. Use the default camera selection setting of "7D", because it has the same size, APS-C, image sensor as your T5. Hopefully,, the link will help you better understand what you are up against.
Try backing off, which increases the apparent DOF, so that you can crop the photo in post-production and processing to the size you want.
A costly tilt-shift lens could probably capture the entire piece in focus in one shot. But, if your best path to getting the entire piece in focus in one image is either, back off the piece and crop the image, image stacking [which photoshop can do], or a T-S lens.
Or, try to reduce the angle at which you shoot the piece. Try to shoot looking straight down at it. This shot is still shooting at angle, but I wound up raising the tripod, and shooting nearly straight down.
