As with all antique furniture, vintage sewing cabinets vary in value depending on a number of factors, including age, condition and the materials with which the item was made. Another important factor is whether the cabinet was mass produced, with rarer examples fetching higher prices.
Vintage sewing cabinets that are highly decorative are likely to carry more appeal to potential buyers than more plain examples. The International Sewing Machine Collector's Society, ISMACS International, provides some useful advice on discovering the value of a vintage sewing machine or sewing cabinet. It may also be useful to find similar items for sale online on websites such as eBay.
