Dear William,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a model 1873, 2-band musket produced by US Springfield. This rifle has a percussion lock and was produced for the US Army. These rifles were produced in a very high number and appear still frequently on the auction market.
This piece is in medium condition and there are no serious damages visible.
An estimation would be between 300 to 600 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
