The “Ready to Serve” Heinz kidney soup still bears its original price sticker and would cost 10d, meaning it was sold before decimalisation in 1971.
The Green Giants niblets corn cost eight pence, according to the package design.
Charity workers believe people wanted to be generous by donating items but may not have realised they were out of date.
Helen Bull, from Cardiff Foodbank where the tins were handed in, said: “Probably what’s happened is that it is harvest time and lots of people clean out their cupboards and donate items that they have never used and don’t really look at them.
“Unfortunately what sometimes happens is that when an older person dies the family will clean out the cupboards and they want to donate and don’t necessarily realise that it was out of date.”
Cardiff Foodbank, which handed out 14,189 three-day emergency food supplies to people in crisis in 2016, tweeted about the find: “It’s a record!! Never had a donation to @CardiffFoodbank with 10d on before! @HeinzUK”
Heinz responded by saying: “Wow! That soup was discontinued over 35 years ago. Should be in a museum rather than a food bank! :)”
Ms Bull, who said it costs between £80,000-£100,000 to run the foodbank each year, added the charity had to waste a lot of food which was out of date.
Leia Trigger, who goes by the name Mermaid Aries, had previously worn her costume to explore the water in the guise of “a mythical, amazing, graceful creature” at the swimming pool in Bromsgrove, Worcestershire.
However, the management has now put a stop to the 18-year-old’s aquatic exploits, citing health and safety reasons.
“It’s mainly the health and safety risk, because the legs are bound together and they worried that I might get into trouble in the water or that I might end up hitting somebody,” she said.
While Miss Trigger’s tail, made of spandex-type material, cost £150, they can be purchased for up to £4,000.
The teenager said she had received positive feedback from others about the costume and is hoping she can find another pool that will allow her to wear it.
She said she was first inspired to try a tail after watching a YouTube video about mermaid outfits.
“But I’m out of action now,” she said.
“It’s more of a case of trying to find somewhere else to swim or seeing if there’s another path I can take with this.
Hamill included a photograph of Star Wars themed undergarments, which in turn caused Prime Minister Trudeau to respond with a tweet of his own.
Including the shorthand for “may the force be with you” – traditional Star Wars phraseology that’s guaranteed to woo fans – the Prime Minister wrote: “Thanks Mark. Sadly those haven’t fit in a while… #MTFBWY.”
Specialist tests showed there was a “remote” chance, the company said, that its production process for the Nitro cold brew range could present a risk of clostridium botulinum, which can cause the rare illness botulism.
It said no illnesses had been reported but that it wanted to “err on the side of caution” by recalling the product.
It has warned anyone who might have cans of the coffee at home to “go ahead and get rid”.
Botulism is a rare and potentially fatal illness which attacks the nervous system and can cause muscle weakness and difficulty breathing.
In a statement, Death Wish Coffee owner Mike Brown said customer safety was “of paramount importance” to the firm.
“We apologise for the inconvenience this may cause our customers and our retail partners, but we believe this is the right precautionary measure to take,” he said.
In the product recall notice, the company said: “Death Wish has undergone a rigorous, lengthy process with an independent, process authority to test the shelf-life, stability and safety of the Nitro Cold Brew coffee.
“After almost four months of ongoing tests, the Nitro Cold Brew has shown no degradation of quality or shelf stability at all. However, in order to ensure industry-leading safety of Death Wish’s cold brew products, a recommendation has been made to add a further step in the manufacturing process behind the Nitro Cold Brew.”
The company said it would refund customers who have bought the product.
