The 139 belongs to the highly traded classic Meisterstücks; in optically and technically top condition, prices of about 1,500 to over 2,000 euros are mentioned, depending on source. The estimates differ, however: an experienced seller regards 2,000 euros as excessive and points to eBay prices at which good pieces sell for considerably less. Dried-up ink is no value-reducing defect; clear signs of use or defects, however, are noticeably reflected in the price. The variant with long or short ink-view window and the original box can additionally influence the achievable price.
