The value of a signed limited edition print is determined by the artist, the quality of the print and the provenance of the particular edition. Prints with a smaller number of editions are generally more valuable than those with larger numbers.
A good place to start when valuing a limited edition print is the quality of the print itself. Certain methods of printing are more reliable and produce higher quality prints. Giclee and screen printing can produce higher quantities of prints because there is less degradation of the original image with each print produced. Other printmaking methods, such as lithography and etching, are not as reliable and can only produce small editions. The edition number is typically recorded as a ratio on the back of the print. For example, 1/100 means that 100 prints were produced in total and this particular print is the first. Prints with smaller edition numbers are often more valuable because they are assumed to be of a higher quality.
Another important factor in valuing a signed limited edition print is its provenance. Provenance is the artwork's history of ownership and is a good tool for proving the authenticity of an artwork. Limited edition prints should come with a certificate of authenticity from the artist and receipts from the previous owners and sellers.
