How the lookup works

Singer assigned serial numbers in factory allotments — recorded batches with a date, quantity and machine class. Those records survive for nearly every prefix (A through Y, plus early no-letter serials from 1851–1900) and were compiled by the International Sewing Machine Collectors' Society (ISMACS). Your lookup runs against 9,200+ recorded allotments covering 1851 to the 1970s.

Two things the records can't do: serials from Singer's Wittenberge (Germany) factory — the C prefix — were destroyed in 1945, and a number that falls between recorded batches dates to the nearest allotment, which is normally still accurate to the year.

Reading your result honestly

Age is the most misunderstood part of Singer values. A machine being 100+ years old does not make it valuable: Singer built tens of millions of them, they were engineered to last, and supply still exceeds collector demand for nearly every model. Ordinary antique Singers — the 15, 27/28, 66, 99 and treadle cabinets — mostly change hands for $55–$200 in working condition. The famous exception is the Featherweight 221/222, a lightweight portable with a devoted quilting-community following.

Frequently asked questions

Where is the serial number on a Singer sewing machine?

On a small plate or stamped directly into the machine bed — usually on the front right corner, near the hand wheel, or on the bed's underside. Pre-1900 machines have digits only; later machines have one or two letters before the digits.

How old is my Singer sewing machine?

Enter the full serial above. The letter prefix narrows it to a factory and era, and the number identifies the recorded allotment batch, which dates the machine to the year it was assigned.

Are old Singer sewing machines worth anything?

Most sell for $55–$200 in working original condition (verified single-machine sales — parts machines and lots excluded). Featherweight 221/222 models are the exception, typically $300–$445 and far more when professionally restored. Ornate early models with pristine decals also carry premiums.

Does the original table or cabinet add value?

Modestly. Complete treadle-and-cabinet sets typically sell in the $15–$100 range; an attractive, undamaged cabinet helps but rarely transforms the price, and shipping costs eat into what distant buyers will pay.
