The original coin holders are always best, unless the holder is damaged or you absolutely MUST have the coin in some company's expensive packaging.
Why do I advocate this? Every exposure of a modern collector coin to the air greatly increases the potential for surface contamination - dust, spots, metal loci. It also increases the likelihood of abrasion, finger prints, moisture, and on an on. The US Mint's handling and packaging systems are much more sophisticated than any TPGs, including positive, filtered airflow, localized ionization, strict objective examination, etc., and the ability to discard any coin that fails.
