Links Without Anchor Text

In my search for linking opportunities I found a limited number of websites on which I can purchase sponsorships for approx $50/month. They are high authority websites, on-topic, with hundreds of authority websites linking to them (those linking sites are in dmoz, and include many edu and gov links).

These sponsorships would normally seem ideal for link placements. The only problem: the links will not use anchor text. They would be small banner ads linked to my home page. There is no possibility of requesting anchor text.

Is there any value in this type of link?
