Hi Richie, the value for your National Collectors Mint Tribute coins would likely be a modest premium over the silver content as there is not a robust collector market for these replicas. Generally, the 4-ounce coins sell for around $100 to $120 (see eBay item 302087364588 though they usually sell for less), the 6-ounce coins would sell for $150 to $200 and the 12-ounce coins would sell for $275 to $350. To find a dealer in your area, you can go to the American Numismatic Association's site or call its headquarters in Colorado Springs ((719)(###) ###-####or Money.org)
