Post Cards, Trade Cards, Visit Cards
One collecting area that is underrated is postcard, visit and trade card collecting. Collecting these items, especially vintage cards or those from a well known person, can be fun, and financially rewarding. The most valuable postcards are those that were made before 1930 which are called “pre-linen”. Cards from that time to the mid 1940s are also in demand. Unless one is very well versed and trained in the art of collecting postcards they may have no idea of how valuable the items may be and in the case of buying them at art auctions they are usually not even announced as part of the available items for sale. This is great for you if you are knowledgeable since you will be able to reap the benefits of knowing what the postcards are actually worth and potentially pick up a great collection relatively cheaply. If you want to get into a fun and very educational hobby then collecting postcards may be for you and if you have children they may find it fun as well. Post cards are relatively cheap to buy, most starting around a pound or so. You can pick up collections at auction and never know what you might find there! Some sell for hundreds but they are rare, but in your search you may find one. Beware of reproductions, obviously, a used and stamped postcard is the best guarantee of authenticity.
