The left-back, 31, signed for Shrews in the summer of 2009 and made 37 league starts last season. He began the current campaign with a loan spell at Rotherham before being recalled in late October and has started 10 of Town`s 14 games since.
But Holden's agent, Clive Hart, insists manager Graham Turner is prepared to let him go over the next week.
"Graham Turner at Shrewsbury has indicated he is willing to let Dean move on this month as he is out of contract in the summer and he feels he has enough defenders at the club," Hart told skysports.com.
"Dean is in the unique position that he could help two clubs win promotion this season having played for Shrewsbury and Rotherham this campaign.
"Dean has a wealth of experience having played in England and Scotland and he still feels he has a lot to offer. We are open to offers and we will weigh up our options before deciding what club to join."
