If the item passes these preliminary tests, consider the purchase. If it's too good to be true, it usually is. There are cases of collectors stumbling upon a desirable article at a yard sale or discovering an under-priced nugget at a shop. As a rule, these happenstances are rare. Be a conscientious consumer.
Most antiques dealers are honest and hard-working.
Treat them with respect and you will gain valued partners who will nurture your basic knowledge and growing collection. Think of a dealer as an advanced collector. The field of antiques is vast, forcing dealers to narrow their focus on one item. Get to know a local dealer. You'll save money, time and effort by learning from their mistakes.
