Lot number - within Auction sales, other domains, etc

Hi Team,

Wikidata recently introduced a new qualifier property called "lot number"

https://www.wikidata.org/wiki/Property:P4775
takes a number; used as a qualifier in combination with new property for
"[[Wikidata:Property proposal/Auction sale]]"; Auction sales are a
significant event for artworks, generally occurring as part of a larger
sale of goods by an art auction house

Besides possibly just using the Product -> additionalProperty
I was curious if there might be a need to directly attach a new property
for "lot number" somewhere....the question is where ?  It seems that you
could also have an Offer which includes many "lot numbers" for a total
price.

Some that I looked at...

http://schema.org/Offer
http://schema.org/Product

Any folks in the Auction Sales domain or Art World ever deal with "lot
numbers" ?
Do other domains such as Gaming, Gambling, Raffles, etc sometimes deal with
"lot numbers" as it pertains to some Prize ?

Thanks in advance,
