For small amounts of money look at ebay. To learn about pricing, go to coinflation.com https://www.coinflation.com/ he has a featured ebay auction every so often and gives limited advice. Mail order I have used before or if you are in the area, California Numismatics https://www.golddealer.com/ or Colorado Gold, http://www.coloradogold.com/ They will answer your question on the phone. If you want help with storage and are more adventurous try Bullion Vault. https://www.bullionvault.com/ You can open an account for any amount, trade at near spot price 24/7 and keep your bullion in Zurich, London, New York, Toronto or Singapore. Your bullion is segregated which means they hold your bullion in your name in the vault of your choice but charge a fee for storage. Good luck
