General rule. The fair market value of the decedent's household and personal effects is the price which a willing buyer would pay to a willing seller, neither being under any compulsion to buy or to sell and both having reasonable knowledge of relevant facts. A room by room itemization of household and personal effects is desirable. All the articles should be named specifically, except that a number of articles contained in the same room, none of which has a value in excess of $100, may be grouped. A separate value should be given for each article named. In lieu of an itemized list, the executor may furnish a written statement, containing a declaration that it is made under penalties of perjury, setting forth the aggregate value as appraised by a competent appraiser or appraisers of recognized standing and ability, or by a dealer or dealers in the class of personalty involved.

Special rule in cases involving a substantial amount of valuable articles. Notwithstanding the provisions of paragraph (a) of this section, if there are included among the household and personal effects articles having marked artistic or intrinsic value of a total value in excess of $3,000 (e.g., jewelry, furs, silverware, paintings, etchings, engravings, antiques, books, statuary, vases, oriental rugs, coin or stamp collections), the appraisal of an expert or experts, under oath, shall be filed with the return. The appraisal shall be accompanied by a written statement of the executor containing a declaration that it is made under the penalties of perjury as to the completeness of the itemized list of such property and as to the disinterested character and the qualifications of the appraiser or appraisers.

Disposition of household effects prior to investigation. If it is desired to effect distribution or sale of any portion of the household or personal effects of the decedent in advance of an investigation by an officer of the Internal Revenue Service, information to that effect shall be given to the district director. The statement to the district director shall be accompanied by an appraisal of such property, under oath, and by a written statement of the executor, containing a declaration that it is made under the penalties of perjury, regarding the completeness of the list of such property and the qualifications of the appraiser, as heretofore described. If a personal inspection by an officer of the Internal Revenue Service is not deemed necessary, the executor will be so advised. This procedure is designed to facilitate disposition of such property and to obviate future expense and inconvenience to the estate by affording the district director an opportunity to make an investigation should one be deemed necessary prior to sale or distribution.

Additional rules if an appraisal involved. If, pursuant to paragraphs (a), (b), and (c) of this section, expert appraisers are employed, care should be taken to see that they are reputable and of recognized competency to appraise the particular class of property involved. In the appraisal, books in sets by standard authors should be listed in separate groups. In listing paintings having artistic value, the size, subject, and artist's name should be stated. In the case of oriental rugs, the size, make, and general condition should be given. Sets of silverware should be listed in separate groups. Groups or individuals pieces of silverware should be weighed and the weights given in troy ounces. In arriving at the value of silverware, the appraisers should take into consideration its antiquity, utility, desirability, condition, and obsolescence.
