It bears mentioning and thoroughly understanding that even an expert typewriter collector or professional repair person can only tell very little of the condition of a typewriter by photos. Does it look generally clean? Are the decals in tact? Does the segment look clean (a vague proxy for the potential condition of the internals)? Is anything obvious missing (knobs, return lever, keys)? Does it look cared for or has it been neglected in a barn for half a century? If it has a case, how beat up, dirty, and water-stained is it?

Most modern typewriters made after 1930 in unknown condition are worth about $5-25 and they peak at about $500 when purchased from a solid repair shop unless some Herculean additional restoration has taken place, they’ve got a rarer typeface, or are inherently actually rare. Hint: unless it’s a pro repair shop or very high end collector with lots of experience, don’t trust anyone saying that a typewriter is “rare”—run the other direction. Run faster if they say it “works, but just needs a new ribbon” as—even at the most expensive—new ribbon is only $15 and their “rare” $600+ machine should have fresh, wet ribbon. The rule of thumb I use is that almost no one online selling a typewriter knows anything about it, including if it actually works. Worse, they’ve probably priced it at professional repair shop prices because they don’t know that in the secondary typewriter market: condition is king.

The least experienced typist will know far more about the condition of a machine by putting their hands on it and trying it out. Does it generally work? Does the carriage move the full length of its travel? Can you set the margins at the extremes and space reliably from one end to another? Does it skip? Is the inside clean or full of decades of dried oil, dust, correction tape, white-out splatter, and eraser crumbs? Does the margin release work? Does it backspace properly? When typing “HHHhhhHHH” are the letters all printed well and on the same baseline? 

Presumably a typewriter at an antique store will meet these minimum conditions (though be aware that many don’t as their proprietors have no idea about typewriters other than that if they wait long enough, some sucker will spend $150 on almost anything). They’ve done the work of finding a machine that (barely) works, housing it, and presenting it to the public for sale. This time and effort is worth something to the beginning typewriter enthusiast, but worth much, much less to the longer term practiced collector.

If everything is present and at least generally limping along, you’ve got yourself a $30 typewriter. Most people can spend a few hours watching YouTube videos and then manage to clean and lubricate a typewriter to get it functioning reasonably. You can always learn to do the adjustments from YouTube videos. (Or just take it to a typewriter repair shop and fork over $200-400 to get things squared.)

If you’re getting into collecting, you’ll make some useful mistakes by overpaying in the beginning and those mistakes will teach you a lot.

Maybe you’re a tinkerer and looking for a project? If so, then find the cheapest machine you can get your hands on (maybe a Royal KMM for $9 at thrift) and work your way through a home study course.

Otherwise, if you’re just buying one or two machines to use—by far—the best value you’ll find is to purchase a cleaned, oiled, and well-adjusted machine from a repair shop. Sure it might cost $350-600, but what you’ll save in time, effort, heartache, searching, repair, etc. will more than outweigh the difference. Additionally you’ll have a range of machines to choose from aesthetically and you can test out their feel to find something that works best for you.

Or, you could buy a reasonable machine like the one typically asked about for $40-70 and find out it needs cleaning, oiling, and adjusting and potentially a few repairs. The repair tab might run you an additional $450. Is it worth it when a repair shop would have sold you the same, a very similar, or an even better machine in excellent condition for $350? It also doesn’t take much work to realize the god-send that a properly packaged and shipped typewriter is worth.

Why Context is Queen

Remember in asking about the cost and value/worth of a typewriter, you’re actually attempting to maximize a wide variety of unstated variables including, but not limited to:

• upfront price and value, 
• information about the current state of the market,
• information/knowledge about the machine itself, its history, desirability/popularity, and how often it’s encountered in the wild, 
• information about how to clean it,
• information about oiling it,
• information about adjusting,
• information about repairing it,
• cost and availability of tools and repair parts,
• and the time involved for both learning and doing all of the above.

The more time you’ve spent learning and doing all of these, the better “deals” you’ll find, but gaining this expertise is going to cost you a few years of life. What is all this “worth” when you just want to type on a machine that actually works as well as it was meant to?

Most of the prognostication you’ll find in online typewriter fora will be generally useless to you because you’re not readily aware of the context and background of the respondents with respect to all of the variables above. Similarly they’re working with no context about you, your situation, where you live, what’s available in your area, your level of typewriter knowledge, your aesthetic, or your budget. You don’t know what you don’t know. At the end of the day, you’re assuredly just as well off to use a bit of your intuition and putting your hands on a machine and trying it out. Then ask: “What is it worth to you?”

If you find yourself asking this question online, but you’re really asking: “Is this $50 typewriter highway robbery?”, the answer is generally: “no”.
