Hello everybody! Today I coer something I chould have years ago. The red book om coins. The title is; A Guide Book of United States Coins. It's something every collector new or expierenced shouls have. Yes, Google and coin websites exist, but the internet is not going to be around forever. Paper will be around forever and let's say the internet is down or something and you need to know a coin's value. This book is the answer. Every single coind that was ever made in the USA is in here, it's PCGS, NGC, and every other coin grader's guide. But by coin graders, for coin collectors. I reccommend everyone get's this book, because it's cheap, accessable, and will outlive the internet probably, THANKS FOR WATCHING!!!!
