D.C. Mun. Regs. tit. 16, r. 16-1105
No auctioneer shall offer any dangerous or deadly weapon for auction without first complying with regulations of the District governing sales of dangerous or deadly weapons by licensed dealers.
If an auctioneer, in addition to being licensed as an auctioneer, is also licensed as a dealer in second-hand personal property under this title, that auctioneer/second-hand dealer shall, upon receiving or accepting any personal property for purposes of sale by auction, keep that property separate and distinct from all other property or merchandise in his or her place of business.
Within twenty-four (24) hours, excluding Sundays and holidays, the dual licensee under § 1104.2 receiving property for sale by auction shall report the receipt or acceptance of that property to the Chief of Police (on blank forms to be prescribed by the Mayor) and retain the property separate in the place of business without selling or otherwise disposing of it, and without altering the identity of the property, destroying the property.
If the property under § 1105.3 is jewelry or other times composed of, or manufactured in whole or in part of gold, silver or platinum, the licensee shall not melt or take apart the items, or obliterate any marks of identification on the property, until after the expiration of fifteen (15) days from the time that receipt of the acceptance of the property was reported to the Chief of Police.
Nothing in § 1105.3 shall prohibit the redemption and removal of any property by the owner of the property at any time; or apply to property purchases by the auctioneer-second-hand dealer from the United States or District of Columbia governments; or apply to sales under or by virtue of legal process.
