Schema.org type for collectibles or catalogs?

There is the coins catalog https://colnect.com/en/coins/list/year/1889

Each item in list has Product Microdata, some items in marketplace have the offers property. For example: this stamp.

Recently the Structured Data Testing Tool began to show error instead of warning for missing offers property on Product pages against it still described as recommended property in product rich result docs. Also here are 'Either "offers", "review", or "aggregateRating" should be specified' errors in Google Search Console.

What kind of structured data will be most suitable for those items?

How to avoid these structured data errors? Will it be correct to have Thing type for catalog items and then change it to Product when the item will be placed in marketplace?

Update 2019-10-15: Structured Data for mentioned above stamp are here. At the moment it has offers so there are 3 warnings only.

And Structured Data for some other stamp without offers, here is the missing offers filed error.

It seems Google does not allow schema.org Product markup without offers.

Hard to answer your issue (Next time please add some code examples).

In general in this URL:

https://colnect.com/en/stamps/stamp/2376-Snowstorm_-_Steamer_off_a_Harbours_Mouth-Birth_Bicentenary_of_JMW_Turner_painter-United_Kingdom_of_Great_Britain_Northern_Ireland

Without this warning:

'Either "offers", "review", or "aggregateRating" should be specified' - But read this: https://www.checkerboard.com/web-development/fix-offers-review-aggregaterating-specified/

Product VS Thing - it's better to use more specific object-type (This is not related to the "marketplace" option to pay Online) (Google rich-snippet related to products).

productontology: For coins/Sports Cards and so on you could add extra-data by productontology (not mandatory): http://www.productontology.org/
