I do save some coins for image purposes. At one time I would need an image of cracks, die chips, machine damage, die wear,
Feeder Finger Damage, die clashes, rim issues, extreme markers, die gouges and ETC. So I have a tube for each item mentioned. When I need an image for something that I don't have. I can find an example and make up an image. I still add to them, but I need them a lot less now. I'be getting closer to 5,000 images on my image host now. (but I'm still adding when I find a new point to cover, something I don't have, something new or a new thought. I have images made up for future questions that have not be asked yet. Images are the best way to teach, so I use them...
A lot!
