Questions to ask R&S Diamond Exchange
We couldn't confirm these from public sources, so ask before you go:
- What would you pay today for a 1 oz American Silver Eagle, and for $1 face value of pre-1965 silver? (Ask two shops the same question to compare.)
- Is an appraisal free, or free only if I sell to you? Do you put it in writing?
- How do you pay for larger amounts — cash, check or wire — and is there a cash limit?
- Do I need an appointment to sell a whole collection?
