Quick verdict
If you need a ready-to-use standard for checking digital scales, the 17-piece weight set at $17.99 is the more straightforward choice: it is a complete kit with a defined 10mg-to-100g working range. If you are building out an inspection bench and want more pieces to work with, the 23-piece gage block and calibration lot at $49.99 gives you a broader assortment, though it is used and the text leaves individual sizing to the photos.

Where each product wins
The 17-piece weight set wins for consistency. It is a defined set with a clear working range and a box to keep the pieces organized. The new condition removes the unknown of prior shop use, and the tweezers make the smallest milligram weights easier to handle.
The 23-piece lot wins for scope. With gage blocks plus other inspection and calibration items, it can cover more varied setups than a single weight kit. That flexibility comes with a tradeoff: the description leaves sizing and labeling details to the included pictures rather than spelling them out in text.
Closer look at the two calibration equipment standards
17Pcs Calibration Weight Set 10mg-100g Stainless Steel Scale Weights Kit
This is a complete, organized starting point for anyone maintaining digital scales. It covers gram and milligram checks, and the included storage box and tweezers keep the smaller weights easy to manage. The coated metal construction and anti-oxidation surface coating support repeated handling. If you are replacing a missing weight or starting a small lab setup, this set gives you the essentials without having to source pieces separately. The limitation is range: if your scale needs a calibration mass above 100 grams, this set won't cover that by itself, so you would need another standard.
23pcs LOT OF MISC. GAGE BLOCKS & OTHER INSPECTION / CALIBRATION EQUIPMENT
This lot takes the opposite approach. Instead of one defined range, it supplies a mixed collection of gage blocks and other inspection/calibration equipment that can be useful when different jobs call for different references. The 23 pieces come from M & J Tooling LLC in Dayton, Ohio. The practical limitation is that this is a used lot, and the wording points to the included pictures for size and labeling rather than providing a list. If you are comfortable working from the pictured specifics, the lot can serve as a varied bench supply; if you need documented dimensions, that level of detail is not offered in the text.
Final choice by use case
Choose the 17-piece weight set if your main job is calibrating digital scales and you want a new, self-contained tool with a defined range. Choose the 23-piece gage block lot if you need a wider assortment of inspection and calibration equipment for a bench and the mixed nature of the lot appeals to you. The right call for most routine scale work is the 17-piece kit; the right call for a more open-ended inspection project is the 23-piece lot.
