Hi 'Dan'. Thanks for posting your item here and welcome to this forum.
I only mention the following to try to help you and all of the members in improving our postings so other members can help better!
It is really necessary for everyone to read the FIRST post from PBK on this forum category. It is so important that I will repeat it here...
Please Read Before Posting Items in "What Is It?"
When posting in "What Is It?", please give members the information they need to help identify your find:
1) Post sharp closeup photos of both the front and the back.
2) State the actual size of the item. Also, if possible, put something with it in the photo for scale: a common U.S. coin, a ruler, etc.
3) If there are any inscriptions which cannot be easily read in the photos, type them in full in your post.
4) If there are maker's marks, numbers, symbols, or other marks on the back which are not easily seen in the photo, post a closeup or a drawing of them.
5) Indicate the composition of the item. For example: "thin brass, filled with lead on the back."
To these great 'rules' I would add
1) -side view photo if necessary, and a photo of the -attachment place (screw hole, ring, etc).
(For your first item without knowing if there is or is not an attachment place its really impossible to say much about your first item. It could be a shoe stud which someone mentioned).
(For your second item the dime what is missing is a photo of the back side...then we can also see what the funny wires are in the photo, now we don't know if the wires are attached to the dime backing).
5) Is it plastic? Is it hollow or solid. (also important for your first item). For your dime, is the backing then aluminum or bronze?
I would myself add another item:
6) the mass or weight of the item if appropriate.
I know when posting objects the most of us forget these 'rules'. Me too, I'm no different than anyone else and forget it also many times. But it does then make a good determination difficult, and if you leave stuff out we will eventually ask the question and you will have to answer it or take another photo anyway...
Also telling us about what YOU think it is helps too. We don't have the object in our hands, that does make a difference.
Better photos and more details are necessary if you want someone to determine what it is correctly. Here is a tip about making a close up photos, one that I had to learn myself. BTW I don't profess to be an expert in this field, its hard to make good photos.
First read again how to make closeups correctly in your manual. For instance I had problems taking close ups until someone else read my manual and told me that before taking the photo the icons that I see in the viewfinder had to turn green before taking the photo, otherwise it won't be in focus. After that it worked find with me. I missed reading that in the manual, or read over it...
Some object are terrible to photograph, you never seem to get them correct. Just keep trying. Try to have good lighting when taking the photos, best for me is hazy daylight.
If still the close up does not work good enough, try taking the photo further away with and zoom in. Then using some free photo editing tool to cut out the object and make it larger. See it that improves the quality.
Anyway I hope this improves yours and all of our postings, I am only trying to help!
