Some things are valuable, i.e. they are of great worth or appreciated for whatever reason. Some other things, however, are not valuable at all to start with, but we can assign value to them by convention or law, for example. This process is called valorization. When something is valorized, it becomes valuable.
I need an adjective to describe things that may be subject to valorization, but which are not valuable yet. Valorizable comes to mind, but it doesn't appear in OED.
I am working in the cultural heritage domain, where almost any conceivable thing may be given cultural value by someone at some point. A thing that has cultural value is valuable. What do you call a thing that has no cultural value (yet), but has the potential to become valuable?
