It would depend on its condition. It would be advisable to get it tuned first, if it is not regularly tuned. Then, call a local music store for an appraisal. If you get it tuned regularly and there are no problems with it, you can probably get a pretty decent price though. Notes:
-The piano will not be worth more than what you bought it for. Steinway pianos are known for this characteristic, but this is not true in the case of a Baldwin. -Appearance will also play a role. If the piano looks shiny and new, it will increase your chances of getting a sale. -Cleaning the keys or having them cleaned will also give an aura of newness.
The value of a 1971 Baldwin piano depends on multiple factors: maintenance, overall care, and size. Therefore, the answer to this question is somewhat subjective, but the information below should give you a good range.
In general, when well-cared for, these are very good pianos. They hold their tune well, and if properly maintained, only need to be tuned every couple of years. Those built during the 70s were 100% made in the US.
To determine the value, first, you need to measure your piano. A piano that is 39'-40' high is considered a console. If it is about 36' high, it is a spinet. Consoles have a better, fuller sound. Therefore, consoles are almost always worth more, but Baldwins are also know for their higher quality spinets.
A well-maintained Acrosonic console (always kept in a temperature-controlled room, frequently tuned and maintained) will average about $1400-1500. One that needs some work, or isn't in quite perfect condition could be $500 or $600. A well-maintained Acrosonic spinet of this age is worth about $400-$900. If it was not well maintained, it probably won't have much resale value. A piano technician would be able to give you accurate insight into the condition.
I personally own a 1971 Baldwin Acrosonic (console) and I love it. I have played the piano for well over a decade, and I bought used. In general, the sound of a Baldwin Acrosonic console is bright, cheery, and very full for it's size.

According to bluebookofpianos.com, an Acrosonic piano with this serial number would have been manufactured in 1964.
A Baldwin Acrosonic was Baldwins designation for its deluxe cabinet style in it's smaller pianos. While it is true that most commonly Acrosonics were spinet pianos, Baldwin also made Acrosonic console pianos. Generally a console piano is one that is 40" or taller and a spinet is a piano that is shorter than 40" down to about 36". Most Acrosonic pianos are now over 30 years old . Back in its hay-day the Acrosonic was considered a very good piano but unless you find one that is in exceptional condition, there are much better pianos available today from makers like Yamaha, Kawai, and even some Chinese made pianos. Today's Baldwin pianos are mostly made in China with a very few exceptions.
That serial number of piano was probably made in 1955.
If it is 50 years old and recently tuned, whatever you can get for it!
