Hi April,

Thank you for contacting Mearto with your appraisal inquiry.
These coins were both issued in large quantities - and so recently - that most are still worth little more than $1.00 UNLESS they have been certified to be in uncirculated mint condition. If that's the case - and it's impossible to adequately assess condition from photographs - they would be worth the following:

2011 P Native American Dollar : Wampanoag Treaty 1621
From the Native American dollar coin series
29,400,000 were minted in Philadelphia in 2011.
The designer/engraver was Glenna Goodacre and the composition of the coin is 88.5% copper, 6% zinc, 3.5% manganese and 2% nickel.
In uncirculated mint condition, this would be worth $5-15

2000 D Sacagawea Golden Dollar
518,916,000 were minted in Denver in 2000
The designer/engraver was Glenna Goodacre and the composition of the coin is 88.5% copper, 6% zinc, 3.5% manganese and 2% nickel.
In uncirculated mint condition, this would be worth $10-20
Both coins sold together would have a value of $15-35*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
