You would have to match yours to the solds on eBay, which range in selling price from 19.95 to 75.00.
When looking at the solds (the range I gave you is for sold--NOT asking--people are ASKING in the hundreds and those sit UNSOLD) you have to comp[are apples to apples--so one with a box, from X year, sells for Y vs one with no box, from Z year which sells for A. Condition also factors in to the mix, so be sure to read that also.
Also look for those with "free" shipping vs. buyer paid shipping. "Free", which means the seller pays shipping and just jacks up the price to cover the shipping.
Remember if you sell online, you will have fees to factor in so your net will be sometimes a lot less than your gross.
If you sell online, be sure to wrap it carefully to prevent breakage.
Thanks for sharing!
I would look in ebay for a similar item. Then filter so you only see the sold items. You will know what it is worth. I sold an item of mine that way.
This is a Lange Skinfold Caliper- it is a precision instrument specifically designed and used for the measurement of tissue (fat) calculation, by Doctors and Fitness professionals. There are a few online for sale through medical stores and online starting at $160 + shipping, asking price - www.ebay.com/
Asking prices are all over the place and these seem to be listed for sale on every online site.
There is no way to tell how many are being sold or what any of those are really selling for except eBay.
Here is a link to eBay's for sale so you can see how the prices are over the top in most cases. Just remember: asking prices are just prices a seller would like to receive for their items but only a sold identical item can be counted as current value as that is the price someone was willing to pay for that item.
Here is a link to eBay's sold listings and you can judge for yourself what is selling and prices actually paid.
That is not to say that people are not still paying high prices online or in stores but we have no way to know how long any of these items have been listed for sale: maybe a month or maybe several months and some will never sell.
If you wish to sell yours you can list it at a high price, take offers and if no offers then lower the price.
