I've recently discovered (I have no idea much late (or not) to the party I am) that there are a bunch of specifcally trained GTP chatbots for a myriad of subjects. I used one for genealogy, and the advice I got (for a research plan) was excellent. Just go to https://chatgpt.com/gpts and you can search on a subject, and it will list the designed chatbots for you. So, I searched on "numismatics", picked one (the specific link is https://chatgpt.com/g/g-67a29d3e068881919730fe236ea3aa75-u-s-coin-collecting-expert), uploaded an image of a coin I was thinking of purchasing, and asked it: "Can you tell me the condition of this coin? And explain why? And its FMV?" (And, just for kicks, I didn't identify the coin). The answer I received was top-notch (and exactly confirmed what I thought the grade and FMV was). (I thought it important to add the "explain why" part) This was a single, simple, question to a one of many coin chatbots. Maybe it will prove useful to me? I dunno. But I was impressed. Of course, YMMV!
