Womad personalised plates and a Womad flag from the first event in 2003 are up for sale.
The plates had never been used, Century 21 real estate agent Chris Wright, who was selling them on behalf of two friends, said.
"Back in 2003 with the first Womad no one knew much about it. No one knew if New Plymouth would get to keep Womad and if it would keep going."
The plates were not bought to use, he said.
"They bought them to speculate. Personalised plates were a popular thing to buy for an investment."
His friends also bought nine Womad flags from the New Plymouth District Council in 2005.
One is up for sale with the plates, the friends are keeping one each and the rest had already been sold, Mr Wright said.
"The [memorabilia] is no longer required. They have reached the stage of life when they want to cash them in."
He had listed the plates and the flag on Trade Me and was looking for about $1200 for the plates, with the flag thrown in.
The flag on its own was worth $200.
With Americarna taking hold in New Plymouth he is hoping someone would buy it for their American car. "Or give it as a present or retirement gift."
Mr Wright said he often sold things of behalf of others.
"I've been approached to sell a few strange things over the years. If it's legal, I'll sell it."
