The set belongs to LEGO's early 12V train system from the late 1960s.
A new and sealed Steam Locomotive is currently valued at around $797, with annual growth of approximately 5%, which is higher than other 12V sets. The average used price is $301 for those in good overall condition. Based on current trends, this set could be valued near $838 within the next year.
Steam Locomotive (721-1) is a very old and rare LEGO set. It has not been available online or in retail stores in good/new condition for over 2 years. Because of its scarcity, the current estimated value of in new condition of $797.37 may be much lower than its true market value. Released in 1969, sealed sets in good condition are especially difficult to find, often commanding a premium well above estimates.
There are currently no new/sealed listings available for Steam Locomotive at this time.
