Would like to know the monetary value of Singer Sewing machine patent #173821.

Thanks!

Hi, brminck!

I hope that you don't mind, but I have combined and re-worded your two posts into what I'm pretty sure what you are wanting as far as asking a question concerning the monetary value of the Singer sewing machine.

We really need more information in order to help you the best here. The patent number doesn't really tell us how old your machine is, the serial number or the model it is. We would need to know at least the serial number in order to start to help you.

Dating the machine according to the serial number is available from the Singer Sewing Machine Company site link below.

If you would like to know how to find the model number on a Singer Sewing Machine, that information is available via clicking on the following link.

If yours is really old, typically, they don't sell for very much. But, much will depend on the condition of it and the way that it's advertised. So, it would also help to know the condition of it.

Is this something that is yours and, if so, has it been in your family for a very long time?

Thanks!
