When selecting a modern doll to buy a number of things should be considered such as quality, number produced, and artist. If you are collecting modern dolls, the most valuable ones will be found at a reputable doll shop. By going to your local doll shop, you may have the chance to meet the artist, and any time you can get to know the person creating the doll, the piece becomes more meaningful and valuable. Dolls sold at department stores are not going to be ones that increase in value over the years. These dolls are fine if you are not buying for an investment, but when you want your collection to increase in value, buying limited editions and artist dolls are your best bets.
Quality is a big factor in the value of a modern doll.
The clothing should be made from quality fabrics, and should be sewn, not glued onto the doll. Painting should be soft and life like without harsh lines and colors. Look for dolls that are handmade by a single artist or dolls that are signed and numbered limited editions. Good luck with your collecting.
