When I was in college, chemistry majors had to take a non-credit course called "The Chemical Profession" which mainly dealt with how to search the library. Now I can use my smart phone...after I get through looking at cat videos.
If "knowledge is power," then access to knowledge (via any search engine) should be a means of empowering ourselves, whether or not it's about coins.
Conversely, there are those who consider themselves so erudite, that they offer opinions at every turn, beyond the scope of their expertise, revealing their intellectual deficiency, and grievous arrogance. I'm sure you recognize them. Their opinions are there alongside those more excellent, and just as often. The difference plainly revealed by the lack of substance, and abundance of caustic opinion. Being offered the suggestion to Google by such a person, would be both refreshingly welcome and much more polite. Sincere thanks to the many who selflessly offer good and knowledgeable thoughts and comments. You are greatly appreciated.
You also have to realize that there is only a small fraction of the known information regarding coins available on the internet. Most of it still resides in books that are not available on the internet. So no matter what search engine you use or how many of them, a lot of things cannot be found on the internet. If you want to know them you'll have to buy the books.
Oh puleeez. Everybody knows that the most significant coin of the century is the South Korean 1970 Bronze 10 Won coin in high M.S. grades. You know what they say about opinions.
Why no, I don't know that saying. Maybe you should spell it out for all of us youngsters. I wonder how many will now go to google the answer.
Ooh ooh, I think I know this one! If you want in one hand and, uh, deficate in the other, see which one gets filled first. Right? Lol
