Inherited 1990 Microsoft Certificate Could Be Worth $60,000, Experts Say
Financial advisers warn that while the certificate could be a valuable asset, it must be validated through Computershare and tax implications regarding cost basis must be considered before liquidation.

A framed stock certificate discovered in a deceased relative's estate may represent a significant financial asset rather than merely a sentimental keepsake. In a recent case study, an executor found a share of Microsoft stock dated March 10, 1990, which has since appreciated in value due to multiple corporate stock splits.
Because of these historical adjustments, the single share from that era is mathematically equivalent to 144 current shares. Current valuations suggest this holding could be worth approximately $60,000, excluding any reinvested dividends. However, this potential value relies entirely on the certificate remaining valid and uncancelled.
Paper certificates were the standard method of representing stock ownership until roughly 1970, designed to prevent counterfeiting and signify corporate importance. The Depository Trust & Clearing Corporation noted in 2021 that it still held $780 billion worth of such paper certificates in vaults awaiting digitisation, indicating that many historical documents remain legally active.
To realise the financial value, the holder must contact the company's transfer agent. For Microsoft, this role is currently held by Computershare. Investors are advised to verify the certificate's validity and initiate the conversion process to cash through the company's Investor FAQ page or by contacting the transfer agent directly.
Tax considerations are also critical when dealing with inherited assets. Special rules apply to determining the cost basis after a death, which can influence capital gains tax consequences. Consulting a tax professional is recommended to ensure the asset is sold or held in a manner that minimises tax liabilities.
If the certificate has been traded or cancelled, it may hold value only as a collectible item. Nevertheless, for certificates that have not been marked as cancelled, the original ownership claim often persists, allowing the estate to convert a dusty memento into a substantial investment for the next generation.
