Hi Dana,

Thank you for contacting Mearto with your appraisal inquiry.

This has me really stumped! I've looked throughout several auction databases (which are the prices Mearto uses to research valuations) and have come up with absolutely nothing comparable. I even reached out to a friend of mine who is an expert in American food advertising and collectibles and he was stumped as well.

Any cans of spam that have sold have been unopened or empty with the top off. Without knowing what this was made for, it's even harder to judge value. If this came to auction, I would not be surprised to see a value of $50-75 on it but wouldn't be surprised if it sold for much more, because of its novelty value.
Based on the photos and information provided, and subject to examination, this is:

An empty lithographed tin SPAM can
late 20th Century
Of standard size, impressed EST.199
CONDITION: empty but unopened tin with pull-tab
$50-75*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
