I have been antiquing for about 4 months learning from my folks who have been doing this for over 5 years. One thing to remember is 1st you can’t know every thing about everything. Focus on a few groups and learn the age, company logos etc … When I say a few groups I am referring to Glassware, furniture, farm equipment, post cards or prints …. If you try to learn about “everything old” you’ll loose that focus. My 2nd suggestion is to read, read and do more reading about the old things you have choose to focus on. Internet is good, but I suggest you get a book too. You can pick a book on most anything you decided on at Barns and Noble or find it here on eBay and help a fellow seller. Good luck! Richard
