YOUR JUDGMENT

Should this image enter PSA OCR?

Judge the full image. The old and new decisions stay hidden until you choose to reveal them.

What qualifies?

One dominant PSA-graded trading card, in a rigid slab with a visible PSA label compartment.
A matching front/back pair of one slab is allowed. Incidental cropped or blurred background slabs are allowed.
Reject multiple distinct sale items, other graders, raw cards, empty slabs, or images without visible PSA evidence.
Use Unclear when the photo does not support a confident decision.

Note optional

Are these changes useful?

Each category has its own random, time-stratified review sample. “SigLIP right” means its decision agrees with your accept/reject label. Unclear and unavailable images are excluded from that percentage.

Do not combine these category percentages into an overall accuracy rate: categories were sampled equally, not in proportion to their frequency.

Sampling and interpretation

Earlier passes are inferred from reaching OCR. Earlier rejects are identified from prefilter batch metadata. A null provider does not prove the old model was Nano. This review measures the value of the observed changes, not a controlled model-only comparison.

For “already rejected by OCR,” a good new reject mainly saves downstream work. For “previously accepted by OCR,” a bad new reject risks losing a usable result. New accepts require OCR before they can recover a usable historical record.
